How many combinations of beverage and cereal can be made?

00:18

Here are the potential answers....

00:22

First, let's count the number of drink choices and the number of cereal choices.

00:26

We count 3 drink choices and 4 cereal choices. We want to figure out how many drink and cereal

00:33

combinations we can make.

00:35

Some potential breakfast combinations could be chocolate milk and Corn Flakes, Orange

00:41

Juice and Froot Loops, 2% milk and Raisin Bra

00:45

We could just list all of them, but that would take a while. There's a better way.

00:49

There are 3 drink choices, and each drink can be paired with 4 different cereals.

00:54

That means all we have to do is multiply 3 by 4

00:58

to get that there are a total of 12 combinations.

01:01

The correct answer is (D).
