Question

A boy has 2 pants and 4 shirts how many different pairs of a pant and shirt can he dress up with​

Answer 1

A boy has 2 pants and 4 shirts.

Let the pants be pant 1 and pant 2

He can were pant 1 with all the 4 shirts.

Which means 4 pairs.

He can wear pant 2 with all the 4 shirts.

Which is equal to 4 pairs.

4+4 = 8 pairs

But you don't need to do all this. You can simply multiply the number of pants with the number of shirts.

2×4 = 8 pairs

Hence, He can have 8 different pairs.

Hope this helps :)
