A league has (9) teams and (2) matches are played between every pair of teams. How many matches will be played?

Answer and explanation

Correct answer: 72

A match-up is formed by choosing any 2 teams from 9, so the number of pairs is \(\binom{9}{2}=\frac{9\times8}{2}=36\). Since each pair plays 2 matches, the total number of matches is \(36\times2=72\). Note that 36 counts only the pairs of teams, not the total matches. Exam tip: use \(\binom{n}{2}\times\) matches per pair for such league questions.
