Let me write this down in another color. So the number of possibilities, let's write this for short, is equal to this 5 times 4 times 3 over the number of ways that I can rearrange three things. Because we don't want to over count for all of these. Viewing this arrangement is fundamentally different than this arrangement. So then we want to divide it by 3 times 2. I want to do that same orange color. Dividing it by 3 times 2 times 1.
