While combinations and permutations are related concepts, they differ in the way they account for the order of the items. Permutations consider the order of the items, whereas combinations do not. In the case of combinations of 3 selecting 2 at once, the order of the chosen items does not matter.
C(3, 2) = 3! / (2!(3-2)!)
Combinations are only useful for small sets.
Why it's Gaining Attention in the US
