Here's your shmoop du jour, brought to you by Pants.

00:06

Without them, belts would look awfully silly.

00:10

How many different outfits can be made from a choice of

00:13

three pairs of pants, four shirts, and two pairs of shoes?

00:16

And here are the potential answers…

00:19

This is a very simple question of combinations.

00:23

A combination is a selection of objects the order of which doesn't matter.

00:27

We are making outfits that consist of shirts, pants and shoes.

00:31

There are 3 things we need to pick, so we have 3 slots.

00:35

The problem tells us we have 4 shirts here, 3 pants here, and 2 shoes here.

00:42

To find the total number of combinations of outfits, we can multiply the three together.

00:47

So, it's 4 times 3 times 2 equals 24. Our answer is (E).
