The Bawden family is shopping for a new television. They are making their decision based on brand and size. The family has 20 possible outcomes for choosing a television. Which is a possible number of brands and sizes that the family has to choose from?

Each brand can be paired with each size, so multiply the number of brands by the number of sizes. For 5 brands and 4 sizes, there are 5 × 4 = 20 possible outcomes. Therefore, “5 brands and 4 sizes” is correct.
