Question 517750
in baseball
you want 4 players -> _ _ _ _
in the first choose you have 12 possibilities, in the second choose you have 11 possibilities cause you cant repeat the player, in the third choose you have 10 possibilities and the last is 9. Now, you must multiply them:
12*11*10*9=11880
but have a problem cause if you choose the players 1,2,3 and 4, for example, and you choose 4,3,2 and 1 is the same players. So you must make the answer correct
caculate the times that the possibilities use the same players together.
after that you calculate it you just must subtract of 11880
make the same with the basketball players.
