The volleyball game is played in 5 innings, with the score of in the first 4 innings and 15 poin

Volleyball. In each game, a team wins 25 points and scores at least 2 more points than the opponent.

Volleyball Tournament Format Regulations:

The first 4 games are played on a 25-point system, and each team will only win 1 game if they win at least 25 points and outperform the opponent by 2 points at the same time.

The official game adopts a best-of-5 system, and the tiebreaker game adopts a 15-point system, after a team scores 8 points first, the two teams switch areas and continue the game in the order of their original positions.

In the tiebreaker (5th game), the first 15 points and 2 points ahead of the opponent wins.

<>Error Analysis] This question focuses on the essence of the probability multiplication formula for independent events, which is to occur simultaneously, as well as the probability of mutually exclusive events. Pay attention to the calculation of the probabilities related to recursion next to the specific solution source.

The key to solving this kind of question is to carefully study the rules of the game, especially to pay attention to the victory or defeat of the last game.

The probability of team A winning team B in a single game is, and the probability of team B winning team A is 1 1) Note that "team A wins three games and collapses" is event a, and hail accompanies Oak "team A wins two games" is event b, then.

The probability of team A's lead in the first three games is p(a)+p(b)=2) If team B wins 3:2 in this game, the first four games should be tied 2:2, and team B wins the fifth game.

So, the probability of the event sought is <>

m = 3 probability of winning A + probability of winning B = + =

m = 4 probability of winning A (not winning three games in a row) + winning B (not winning three games in a row) = ( c(3,4)- 1) (

m=5 probability = (c(3,5)- c(3,4)) expectation=3

In 1900, the game ended with 21 points. In 1912, the game ended at 15 o'clock. In 1923, it was changed to 14 and it took 2 points in a winning streak to end.

In 1988 it was a 17-point scale. In 1992, it was changed to a 17-point system with a 2-point lead in the first 4 games, and a 14-point system with a 2-point lead in the tiebreaker. In 1998, it was changed to a 25-point scale with a 2-point lead, and a tiebreaker was a 15-point scale with a 2-point lead.

There have been some before. The premise of a 15-point win is that the team with 15 points first must be 2 points ahead of the opponent to win.

In 1912, it was stipulated that players on both sides had to rotate positions. In 1917, 15 points per game were established. In 1918, it was established that only the serving team could score points in volleyball (except for tiebreakers). When the receiving team wins by one goal, they get the right to serve (

If there is a 2-point lead, the team that reaches 15 points first wins; If you are only 1 point ahead, the team that reaches 15 points first does not win, and the game continues until you are 2 points ahead!

Prior to 1998, volleyball was based on a service point system with 15 points per game. The maximum score limit for the first four games is 17 points. When the score is 16:

At 16 o'clock, the team with the 17th point won the game with only one point ahead. There is no maximum score limit for the tiebreaker (5th game), and when the score is 14:14, the game continues until a team leads by 2 points.

On October 28, 1998, the FIVB decided to change to a 25-point per game system. The first four games to score 25 points in each game wins, the fifth game to score 15 points first wins, if there is a 24 draw or 14 draws, you must continue the game until a team leads by 2 points to win. The tiebreaker (fifth game) is still 15 points, when the score is 14:

At 2 p.m., the game continues until one team leads by 2 points.

A test question analysis: Team A wins in 2 situations: 2 consecutive wins in the second game, the probability is <> In the second game, Team A loses 1 game, and wins the 3rd game, the probability is <> Therefore, the probability of team A winning is p=p1

p2<>

The probability of occurring at the same time is multiplication.

In the first three games, the probability of Team A leading Zheng Coarse.

There are three scenarios.

A wins, B wins, A wins.

A wins, A wins, B wins, and the ants are trapped.

B wins, A wins, A wins.

Each of them is. The probability of Team A's lead is 3*

Similarly, there are C(5,2) cases where Team B wins 3-2 in this match.

then c(5,2)*

The probability of Team B winning 3-2 in the match is a dull thought.

Summary. The start of the tournament is registered, and the start time of the bureau is registered.

The first serve is crossed on the number 1 in the first round ** of the first serving order of the starting team to indicate that the player in that position serves, and at the same time, the " " sign is drawn in the first round ** of the receiving team to indicate that the team receives the serve. When scoring, the team on the right side of the cumulative score on the "" sign, after losing points, first on the opponent's score accumulation points on the "" sign, and then on the 1 number in the service round **, and finally the team that lost the team to record the accumulated points in the first round ** of the side. Subsequent rounds are recorded, and so on.

When the 6 players have finished the first round, the service round will be recorded from the number 2.

4.Notes on the working methods of the recorder (see volleyball match score sheet).

When a team requests a timeout, the score at the time of the timeout is noted in the box below the team's cumulative score, and the substitution method is required.

Fifth game recording method: When a team scores 8 points, the referee should be notified in time to let the players change the field area, and move the left team's serving order and player number on the score sheet to the corresponding column in the second half of the right game. The "-" horizontal line is drawn under the cumulative score on the left and right of the original to indicate the score obtained by both sides before the change.

The team that moves to the right also draws a "-" horizontal line under the score scored, and the score is registered from then on. The service rounds continue to be recorded in turn, and the content of the left team's substitutions and pauses column must also be changed to the corresponding column on the right.

At the end of a game, a circle should be drawn on the final score of the two teams to indicate the final score of the team, and the end time should be filled in with the extra score in the points column.

Warnings and penalties for delayed matches and warnings and penalties for misconduct are recorded in the corresponding column at the bottom left. Draw a circle on the points awarded for the penalty imposed on the opponent.

In a regular volleyball game, if a player wins four goals in a row, the scoring order is.

This question is up to me, it takes a little time to type, so please be patient.

In a regular volleyball game, if a player wins four goals in a row, the scoring order is.

Summary. Hello dear <>

As far as the teacher knows: scoring rules for volleyball games.

Serve. Six players on each side take turns serving in a clockwise direction. Each time the team has the right to serve, the player who serves the ball into the opponent's half in the back right corner of his own half to start the game again.

The server can serve with an upper or lower hand, with a fist, an outstretched finger or an arm. The serve can be teed off at any point behind the baseline, but the rules allow the player who makes the jump serve to enter the court when it lands. The volleyball can land anywhere in the opponent's half, and the serving player will continue to serve until the team loses the serve.

Score. Under the new scoring rules, one team scores at the same time as they gain serve, the so-called per-ball scoring system. The game consists of five innings.

In the first four innings, the winning side must reach 25 points, or on top of that, two points higher than the opponent. The winner of the fifth game only needs to reach 15 points, or two points higher than the opponent on top of that.

In a regular volleyball game, if a player wins four goals in a row, the scoring order is.

Hello dear <>

According to the teacher's understanding: volleyball game scoring rules, six players on each side of the serve in a clockwise direction in turn. Each time the team wins the serve, the serving player sends the ball into the opponent's half in the back right corner of the side and starts the game again.

The server can serve with an upper or lower hand, with a fist, an outstretched finger or an arm. The serve can be teed off at any point behind the baseline, but the rules allow the player who makes the jump serve to enter the court when it lands. The volleyball can fall anywhere in the opponent's half, and the player will continue to serve until the team loses the serve.

ScoringUnder the new scoring rules, the round side is required to score points at the same time as they gain serve, the so-called per-ball scoring system. The game consists of five innings. In the first four innings, the winning side must reach 25 points, or on top of that, two points higher than the opponent.

The winner of the fifth game only needs to reach 15 points, or two points higher than the opponent on top of that.

The Liberty's new Libero will be a defensive specialist who can make any substitutions in the back row to help the team defend against the opposition's attacks. Libero is not allowed to serve, block the net or go around the front row, so it is usually played by a player who is small but agile and can quickly fall to the ground to save the ball so that the game can continue. The libero is free to change and for ease of distinction, the libero will wear clothes of a different color from the other players.

SubstitutionsAccording to another modified rule, the J Coach can stand and give orders to the team during the game, but must stay in a specific area. Including substitutions, the coach has a total of 6 substitutions per inning. A substitute may substitute a starter or be replaced by the same player.

I can find out all of these for myself, that's why I asked you.

That's how his rules are.
