Terrell Stark · Answer 1

It's a combination because the order they are chosen doesn't matter.

example: (A, B, C) = (C, B, A) = (B, A, C) ... etc.

combination choose 4 out of set of 10

10Cr (4) = 210 ways to pick 4 committee members from a group of 10

Samuel Hanna · Answer 2

10! / (4! * (10-4) !) = 210 different ways
