A restaurant offers dinners with a choice each of two salads,six entrees,and five desserts

Answer 1

I will guess that your question is: "How many different dinners are possible?"

Since a salad is different from an entree, which is different from a dessert [no overlap], we use the fundamental counting principle which says we can multiply category sizes when they do not overlap...

2 • 6 • 5 = 60

So there are 60 different dinners possible.
