1. ## permutations

Can someone explain what the steps for solving the following problem. Space shuttle astronauts consume an avarage of 3000 calories a day. One meal normally consists of a main dish, a vegetable, and two different disserts. The astronauts can choose between 10 main dishes, 8 vegetables, and 13 disserts. How many different meals are possible?

If it's not 10 x 8 x 13 I will learn something on this thread unless the calorie counts of each food group counts. Then I may still learn something.

That would be the right answer if they only wanted one dessert. But the question stipulates two desserts. The logic you use is still correct but you need to account for all possible dessert combinations now.
