You can put this solution on YOUR website! A menu at a restaurant offers 9 different appetizers. How many different ways can a group order 4 appetizers?
-----------------
9*8*7*6 = 3024
But since a group of A, B, C & D is the same as B, D, A & C, there are 4*3*2*1 = 24 ways to order any group.
3024/24 = 126
