There are 97 different ways to wear a skirt or a pant with each ensemble.
Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.
A combination, for instance, is choosing five people to be in a group where everyone plays the same job regardless of how you pick them up. It is a permutation, though, if you're choosing five people and their roles depend on the order in which you choose them.
There are 5 pairs of pants, 7 skirts, and 12 shirts.
=5C2 + 7C2 +12C2
= 10 + 21 + 66
