There are girls and boys in a chess club. The club holds a round-robin tournament in which every player plays against every other player exactly once.
What fraction of the games are boy-versus-boy? Enter your answer as a fraction in simplified form.
+1005 How many girls and boys? I don't think I can solve the problem without this, since it's looking for the proportion.
25 combanations, so total is 3628800....... simplify \(\frac{25}{3628800}\)which equals \(\frac{1}{145152}\)
+1005 I'm afraid I don't understand. Are you the person who asked the question, and if yes, could you please inform me of how much of each gender? Thanks.
