In a tournament of 8 players, each player plays every other player once. How many matches are there?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 28.
We have 8 players, and each player plays every other player once.
That means we need to count the number of unique pairs of players. Each match is a pair of two players.
The number of ways to choose 2 players out of 8 is: (8 × 7) / 2 = 28
