There are 5 girls and 5 boys in a chess club. The club holds a round-robin tournament in which every player plays against every other player exactly once.  How many games are payed in total?

There are ten players total ( does not matter that some are boys, some are girls)

   each must play 9 other players     10 * 9 = 90  games 

                                              BUT each game involves TWO players...so divide by 2 to get   45 games must be played
