Ted is hosting a dinner party. He has a the choice of serving chicken, pasta, or hamburgers for the main course;carrots, lettuce salad, or pineapple for the side dish; and ice cream or cookies for dessert.
How many combinations of one main course, one side dish, and one dessert could Ted serve? If Ted chooses his menu at random, what is the probablility that he will serve pineapple for the side dish?
I think Ted can serve 18 combinations. I multiplied 3 by 3 by 2. I think the probablilty for pineapple will be 1/3.
