Step-by-step explanation:

Given the following information:

3 different sandwiches
2 different salads
5 different drinks

Let assume that the combo contains: 1 sandwich, 1 salad, and 1 drink

Hence, we have:

The total possible ways of choosing sandwiches she can choose is: 3

The total possible ways of choosing salads she can choose is: 2

The total possible ways of choosing drinks she can choose is: 5
