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

he has four choices for what to wear as trousers, seven for shirts, and three for jackets. therefore the answer is 4*7*3 or 84.

 

HOPE THIS HELPED!
