Question

Suppose Ruth Ann has 3 routes she can choose from to get from school to the library, and 5 routes from the library to her home. How many routes are there from Ruth Ann’s school to her home with a stop at the library?

A) 9 B) 60 C) 15 D) 25

Answer 1

There are fifteen routes as each of the three library routes can go to any of the five routes to home.

Answer 2

Answer: C) 15

Explanation:

The number of routes Ruth Ann can choose from to get from school to the library = 3

The number of routes Ruth Ann can choose from the library to her home= 5

Therefore, the number of routes she can choose from Ruth Ann’s school to her home with a stop at the library =
`3*5=15`

Hence, there are 15 routes from Ruth Ann’s school to her home with a stop at the library.
