1 How many seconds does it take for a player to serve a ball from outside the bounds?

Seconds rule. When a team is in possession of the ball, players of the same team must not stay in the opponent's penalty area for more than 3 seconds. In the event of a throw-in during play or after possession, if a player from the same team stays in the penalty area for more than 3 seconds, the referee immediately blows the whistle and awards a 3-second penalty.

2. The five-second rule.

When a player with the ball is heavily defended but does not pass, pitch, roll, or dribble for five seconds, it is also known as a foul. In the past 5 seconds, the scrum was awarded for an offence, but now the opposing player throws it in the nearest place.

Seconds rule. A team that has the ball from the back court must advance the ball to the front court within 8 seconds, otherwise it will be fouled and the opponent will throw the ball in.

Let me tell you about the rules of the FIBA game.

3.It should be a scrum. But the current rule is that if team A gets the ball at the opening jump, then when the first time it encounters such a situation, or when it encounters a situation where it needs to scramble, team B serves, and the second time team A serves. Look at the options, you should choose A

Breaking through with the ball means breaking through with the ball. A back turn is an action after stopping the ball.

The first three are OK, the last two are not so sure.

There are 1024 different ways to pass, and the problem of permutations and combinations, the first five times are 4 to 1, and the last time is 1 to 1, so it is 1024.

Permutations and combinations are the most basic concepts of combinatorics. The so-called arrangement refers to taking a specified number of elements from a given number of elements and sorting them. Combination, on the other hand, refers to taking only a specified number of elements from a given number of elements, regardless of sorting.

The central issue of permutations and combinations is to study the total number of possible scenarios for a given required permutations and combinations. Permutations and combinations are closely related to classical probability theory.

Introduction to Probability:

Probability, also known as "probability", is a reflection of the probability of a random event occurring. A random event is an event that may or may not occur under the same conditions.

For example, from a batch of ** and defective goods, randomly draw a piece, "draw **" is a random event. Suppose n experiments and observations are carried out on a random phenomenon, in which event a occurs m times, that is, the frequency of its occurrence is m n.

The problem of permutations and combinations, the first five times are all 4 to choose 1, that is, C41, you know the meaning of C41, right? The last time is 1 out of 1

The calculation yields 4*4*4*4*4*1=1024

This is a combination problem in the second year of high school, which is equal to when A serves, because the probability of receiving the ball is equal, there are 4 people in addition to A, so there are 4 possibilities, after the second person receives the ball, because A can not receive the ball, so there are 3 people who can receive the ball, and the third person can pass 3 people, and so on, so there are 3 possibilities from the 2nd to the 5th time, and the last pass back to A's hand, so there is only 1 possibility. So it's 4*3*3*3*3*1 = self-counting.

1. After a successful shot or the last free throw:

1. Any member of the opposing team of the scoring team has the right to throw a throw-in on the end line or at any point behind the end line at the middle basket.

This is also appropriate when the referee hands the ball to a player or after he has made it available to him after a time-out or each stoppage of play.

Use. 2. He can pass the ball to a player on the same team who is on or behind the end line, but the first player from outside the line can handle it.

The moment of the ball is counted as 5 seconds (see paragraph 3 below).

3 Gates do not have to hand over the ball unless it allows the game to restart faster.

4. After the ball is basketed, the opposing player who throws the throw-in is not allowed to touch the ball.

Accidental or unintentional touching of the ball is permissible, but it is a technical offence if the ball is interfered with in order to delay the game.

Rules. Exceptions:

In the case of a technical foul or disqualification of the coach registered and (or) a player for unsportsmanship or disqualification.

After a free throw for a qualified foul, regardless of whether the last free throw was successful or not, it must be at the midpoint of the sideline opposite the recording table.

throw-in.

2. After a violation or each stoppage, throw a throw-in to restart play (after a successful free throw or a layup).

Except): 1. The player of the throw-in team shall stand outside the bounds closest to the place of violation or stop play designated by the referee, but directly position.

Except behind the rebound (exception: see note 1).

2 Gate North The ball must be handed directly to the player who took the throw-in or placed in a place where the player can handle it.

3. The throw-in player shall not move laterally from the place designated by the referee before the ball leaves his hand.

about 1 meter) and move in more than one direction.

1) It is allowed to move some small steps in one direction, as long as the total distance does not exceed a normal one;

2) As long as the surrounding situation allows, the team members can retreat as far as the vertical line is.

3. A player throwing a throw-in shall not violate the following rules:

1. Make contact with the ball in the field before it touches another player;

2. Step on the field when the ball leaves the hand;

3. The time consumed before the ball leaves the hand is more than 5 seconds;

4. Throw the ball over the rebound and pass it to another player on the court;

5. After throwing the throw-in ball out of hand, before the ball touches the player on the court, the ball touches out of bounds or stays on the hoop neck, or.

into the basket. 4. No other player may cause any part of his body to cross the line before the ball has crossed the line.

Violation of Rule 2.3Paragraphs 3 and 4 are violations.

Penalty The ball is awarded to the opposing player to take the throw-in at the place where the throw-in was taken.

Note 1. If a free throw or layup is invalid, the subsequent throw-in will be on the extension of the free throw line.

2. The referee may throw the ball to the player who throws the throw-in, as long as:

1. The goalkeeper is not more than 3 or 4 metres from the throw-in;

2. The throw-in player stands in the correct place designated by the referee;

3. The team with the ball does not receive benefits.

3. When the edge of the field is less than 2 meters away from the out-of-bounds obstacle, no player from both sides is allowed to stand at a distance to throw the throw-in.

team members within a distance of 1 meter.

Such a situation is against the law. According to the rules, a throw-in is not thrown in until it has been thrown (without leaving the throwing player's hand) and no part of the body is allowed to go out of bounds by other players. And if you touch the ball out of bounds, of course, your body is out of bounds.

You are also not allowed to be within 1 metre of the throw-in, so you are against the law. Please see the relevant provisions of Article 17, Paragraph 3 of the Basketball Rules:

In the throw of the ball into bounds, the other players should not:

Cross any part of your body before the ball is thrown across the line.

When there is less than 2 metres between any obstacle outside the boundary of the place where the throw is made and the boundary, the player who is close to the place where the throw is made is within 1 metre.

A breach of subsection 1 is an offence.

The penalty is awarded to the opposing player to throw the ball into touch at the spot where the ball was originally thrown.

Hello playing half-court basketball when the opponent scores, it is an amateur entertainment, and when one side scores a goal in basketball, it is still the scorer's serve.

Whether it is half court or full court, the situation when the ball goes out of bounds depends on which side is the last person to touch the ball, and the last side to touch the ball must not have the ball, and the opponent must re-serve.

Generally, it is on the serve when it is out of bounds.

For example, the bottom line is out of bounds, and the side of the line is out of bounds.

This can't, the defender steps on the line to defend, the referee will remind you, if the steal is successful, it doesn't count.

A basketball game is a game that is played according to the sport of basketball. There are various forms of basketball games, including the more common five-a-side basketball, and the now popular street three-on-one basketball game, which is a three-on-three game and pays more attention to individual skills.

Backboard (West El Tablero): Both sides of the backboard should be made of transparent material, preferably reinforced safety glass, which is as hard as wood three centimeters thick. The size of the backboard is one meter wide, one meter vertical height, and its lower edge is at least one meter from the floor.

The surface of the rebound should be flat, and a rectangle of 59 cm wide and 45 cm high should be drawn on all sides from the outer line, and the upper edge of the bottom line of this rectangle must be connected with the upper end of the hoop.

Basket (West El Canasta): The basket consists of a hoop (West El Aro) and a Nets (West La Red). Hoop - made of solid iron, with an inner rim of at least 45 cm and at most cm, painted orange.

The diameter of the metal hoop is a minimum centimeter and a maximum centimeter. Nets - shall be white, suspended from the hoop for the purpose of providing a slight resistance to the ball after it has been placed in the hoop, and shall have 12 mesh mesh to be suspended from the hoop, with a minimum length of 40 cm and a maximum length of 45 cm.

Ball: The basketball must be a round body, orange in color, and the outer skin must be made of leather, rubber or synthetic materials, weighing between 600 and 650 grams and having a circumference of 75 to 78 centimeters. The degree of air pressure in the ball shall fall on the playing field at a height of about one meter from the bottom of the ball, and its height shall not be lower than or higher than the meter from the top of the ball.

When a player touches the ball, he must be in bounds and must not go out of bounds or step on the line, otherwise it is considered a violation. As for the no-players, it doesn't matter if they are out of bounds or not.

Yes, there is no rule on the basketball court that says that you must be on the court, but if you touch the basketball outside the court, even if your own ball goes out of bounds, the opponent will have the ball.

No, the referee will only kick off if all the players on the pitch are in bounds (except for the server player).

In basketball, when the opponent takes a throw-in:

1. The defender shall not go out of bounds (in space, the boundary is three-dimensional), otherwise, the referee shall immediately blow for the violation, re-serve and re-time for five seconds;

2. After the throw-in player gets the ball from the referee, the cumulative sideways movement shall not be greater than 1 meter, otherwise the violation will be blown immediately;

3. When the distance between the boundary of the player throwing the ball and any obstacle outside the boundary is less than 2 meters, the player who is close to the throwing ball into the line shall not be within 1 meter, otherwise the violation will be immediately awarded.

Note that if you want to blow for a violation, the five-second throw will be re-timed, otherwise it will be unfavorable to the throwing party.

Note: A player who throws a ball into touch should not be whistled for a violation, and only if he steps into bounds should be whistled for a violation.

Because, the boundary is also part of the boundary.

5 passes, the first pass is fixed for A to pass, 4-a-side basketball has 3 choices for each pass, and the last time to catch the ball is only one way A, so the most passing methods are 3*3*3*3*1=81;

Since A receives the ball, all combinations of A receiving the ball in the previous pass must be excluded.

The last time A receives the ball, so the fifth passer cannot include A, so the fourth pass to A must be removed, as above, the fourth time A receives the ball 3*3*3*1=27;

Similarly, the third transmission to A is: 3*3*1=9;

The second time is 3*1=3;

It can be obtained: n = 81 - (27 - (9 - 3)) = 60 times.

If you choose one of the four people and start passing, after 5 times, there are a total of 3 5 * 4 situations (because the first selection has 4 options), so the last ball is passed to A There are 3 5 cases, if the first ball is also sent from A, it must be related to 3 5 4, so it must be 60

Article 9 The beginning or end of a match or section.

In jump balls, the first quarter begins when the ball leaves the referee's hand.

When a ball is thrown into touch, when the ball is handed to the player who threw the ball into touch, all other quarters begin when the ball is in the stage where the ball is in touch for the player who throws the ball into touch.

The above is the original text of the 2010 version of the current [Basketball Competition Rules] for throwing the ball into bounds, which means that the clock starts when the referee hands the ball to the player who sent the ball out of bounds. Throwing the ball throwing the ball into the realm [Basketball Competition Rules].

The time when the players on the field receive the ball will be counted from the beginning.

When throwing a throw-in, the defending team must not cross the boundary (three-dimensional), otherwise the referee shall immediately blow for a violation.

If the title says "The defending team throws the ball into touch off", the defending player's arm crosses the bounds and should be whistled for a violation;

The basketball fell on the player who threw the ball out of bounds, which is a follow-up action and will not be pursued.

In summary, the defending team was awarded a penalty when the defender's arm was extended out of bounds during the throw-in, and the ball was re-served and the timer restarted for five seconds.
