Question

a restaurant offers 9 appetizers and 10 main courses. in how many ways can a person order a two - course meal?
there are \square ways a person can order a two - course meal.

Explanation:

Step1: Apply the fundamental counting principle

The fundamental counting principle states that if there are \(m\) ways to do one thing and \(n\) ways to do another thing, then there are \(m\times n\) ways to do both things. Here, \(m = 9\) (number of appetizers) and \(n=10\) (number of main courses).

Step2: Calculate the number of combinations

We calculate \(9\times10\).

$$9\times10=90$$

Answer:

\(90\)
