-How many ways can you order a dinner that contains 1 salad and 1 entree?
-How many ways can you order a dinner that has 1 entree and 1 dessert?
-How many ways can you order 2 different salads?

Answer 1

Step-by-step explanation:

1.)1 salad and 1 entree

We need to choose 1 salad out of 5 so it is in 5C1 ways and 1 entree out of 6 so it is in 6C1 ways. As and is mentioned it will be multiplication. So the answer is 5C1 * 6C1.

2.) 1 entree out of 6, so it is 6C1 and 1 dessert out of 3 so it is 3C1. As and is mentioned again, it will be multiplication. So the answer is 6C1 * 3C1.

3.) Now we can order 2 different salads in 5C2 ways.
