(# of appetizers) * (# of entrees) * (# of vegetables)
For example, consider the following sets on the menu
appetizers = { onion rings, jalapenos, wings}
entree = { salmon filet, chicken, steak, pork chop}
vegetable = { corn, broccoli, carrots, salad, mashed potato}
then there are 3 * 4*5 = 60 combinations
