Answer 2

Calculation of the Number of Games Played

To calculate the total number of games played in the tournament, we need to determine the number of pairs of players and multiply it by the number of games each pair plays.

Given that there are 6 participants in the tournament, we can calculate the number of pairs using the formula n(n-1)/2, where n is the number of participants.

In this case, n = 6, so the number of pairs is (6 * (6-1))/2 = 15.

Since each pair plays one game, the total number of games played is 15.

Calculation of the Number of Games Played by Each Participant

To calculate the number of games played by each participant, we can divide the total number of games played by the number of participants.

In this case, the total number of games played is 15 and there are 6 participants. Therefore, each participant played 15/6 = 2.5 games.

Since we cannot have a fraction of a game, we can assume that each participant played 2 games, with some participants playing an extra game to make up the total number of games.

Calculation of the Total Points Earned by All Chess Players

To calculate the total points earned by all chess players, we need to know the scoring system used in the tournament. Without this information, we cannot provide an accurate answer.

Please provide the scoring system used in the tournament (e.g., 1 point for a win, 0.5 points for a draw, 0 points for a loss) so that we can calculate the total points earned by all chess players.
