## Homework Statement

How many different arrangements can be made with these 5 cards?

There are 5 different cards laid out next to each other. How many different arrangements can be made so that one of the inner cards is never on either end?

## Homework Equations

None, probably

## The Attempt at a Solution

I know the answer (72), but I have no idea how to get it. It's basic probability, so there should be a simple way of getting it (i.e., no formulas)...

I tried 25

^{2}minus 5 because I didn't know what else to do.

Can someone help guide me?
