In how many ways can four people be chosen from a group of 15 people to take out the trash after a party
=============
If there's no distinction between them:
15*14*13*12 = 32760 ways.
----
But, choosing A, B, C & D is the same as B, D, A & C, so each group can be chosen 4,3,2,1 ways = 24
----
32760/24 = 1365 ways
