Question

Elmo decided to take two classes

during summer school. For first period,
he can choose either math or English.
For second period, he can choose
either art, music, drama, or cooking.
How many different schedules of two
classes are possible?

Answer 1

There are a total of 8 different schedules.

Explanation:

In situations like these, it's best to write down all possible combinations on a tree diagram. However, I use a different way to solve problems like these. For the equation multiply the choices of the first period with the choices of the second period. 2×4=8

You can do this other problems that can include 3 choices, 4 choices, and so on.
