Hello, suppose ten table tennis players are numbered 1 to 10, the first pair of players can choose two from Zhongrenshan, and there are 2 ways to choose out of 10, that is, C(10,2). After the first pair is selected, two more of the 8 players who are left to play against each other will be selected, and there are 8 selections and 2 selections, that is, C (8, 2). After the second pair is selected, two more of the remaining 6 players are selected to compete against each other, and there are 6 selections and 2 selections, that is, C (6, 2).

A score is awarded to one team when:

1) Failure to serve legally;

2) failure to lawfully fight back;

3) After hitting the ball, the ball does not touch the opponent's table area and crosses the opponent's end line;

10) The doubles player hits the ball in the wrong order;

The second question: B2 should serve and A1 should receive the serve.

From the beginning of this game, A1 serves first, after B1 receives serve, both sides score and serve for 2B1 first, and after A2 receives serve, both sides score and sum is 4

After A2 serves first and B2 receives the serve, both sides score a sum of 6

B2 serves first, A1 receives serve. Both sides scored a sum of 8.

In doubles, each time a serve is changed, the front receiver should become the server and the partner of the front server player should become the receiver. ）

1. If the order of receiving the serve is wrong, and the referee or the opposing player points out during the game, the serving side will be awarded a score, 2. If the order of receiving the serve is wrong, and neither the referee nor the opposing player points out during the game, after the end of the round, the opposing player and the referee point out that the score should be awarded according to the result of the game. The rest of the game went on as usual.

Once the referee discovers that the order of serving or receiving the ball is wrong, he shall immediately suspend the game and follow the order established at the beginning of the match, according to the score on the court, the player who should serve or receive the ball shall serve or receive. In doubles, the game is played in the order established by the first player to serve at the time the error is discovered. Once the referee finds that the players should change positions but do not do so, they shall immediately stop the game and correct the correct position of the players in the correct position of the player with the score on the field in the order established at the beginning of the game, and then resume the game.

In any case, all scores until the error is found are valid.
