Roberto has four pairs of trousers, seven shirts, and three jackets. How many different outfits can he put together if an outfit consists of a pair of trousers, a shirt, and a jacket?

He has 4 ways to choose a pair of trousers, 7 ways to choose a shirt, and 3 ways to choose a jacket.

Therefore, answer is **\(4\cdot7\cdot3 = 84\).**

We could count it out, but that would take a long time.

We could make a pairing tree, but there is an even easier way!

If we just multiply the numbers, we get the total number of outifts! \(4\times 7\times 3=84\).

You are very welcome!

:P
