Question

To decide what to eat at a restaurant, Frank closes his eyes, places his finger on the menu, and orders whichever dish he places his finger on. He chooses one salad, one main course, and a dessert. If there were 10 possible dishes for each selection, how many possible combinations could he have chosen other than the one he selected?

Answer 1

C.999

Explanation:

Answer 2

There are 10 possible salads, 10 possible main courses,
and 10 possible desserts.

If a meal consists of 1 salad, 1 main course, and 1 dessert, then
he could have picked (10 x 10 x 10) = 1,000 different meals.

There are 999 other possibilities besides the one he picked.
