jason wants to choose 9 players for his track team ,there are 12 players to choose from.how many different teams can jason make?
Schach [20]
He could only make one team, considering that if you do 12-9, you are left with 3, and Jason wants to have his team consisted of 9 players. However, if you make 3 teams with 4 players on each team, or 4 teams with 3 players on each team, you could do that as well.
