Question

A restaurant menu has four kinds of soups, five kinds of main courses, five kinds of desserts, and five kinds ofdrinks. If a customer randomly selects one item from each of these four categories, how many differentoutcomes are possible?

Answer 1

We have to use the multiplication principle as we have 4 independent events (4 categories) and they can happen in a certain number of ways.

4 ( kinds of soups)* 5 (kinds of main courses)* 5 (kinds of desserts)*5(kinds of drinks)= 500

The answer is 500 outcomes.
