Question

There are 13 brunettes and 7 blondes in a Spanish class. The teacher selects two students to run an errand. How many possible outcomes are there if she selects a brunette followed by a blonde?

Answer 1

91 possible outcomes

Explanation:

As the teacher selects a brunette followed by a blonde, we just need to find the number of possibilities of choosing a brunnette and the number of possibilities of choosing a blonde:

number of possibilities of choosing a brunette: 13

number of possibilities of choosing a blonde: 7

Then, the number of possible outcomes is the product of these number of possibilities:

13 * 7 = 91 possible outcomes
