Question

A sales representative can take one of 4 different routes from City B to City E and Amy one of 5 different routes from City E to City H.

How many different routes can she take from City B to City H, going through City E?

Answer 1

20

Explanation:

Since you have 4 different ways to do the first part and 5 ways to do the second part, the fundamental counting principle states that you multiply the number of ways.

4 times 5 equals 20.
