Suppose that pizzas can be ordered in four sizes (small, medium, large, and Illini-size), with three crust choices (thin, thick, and Chicago style), four choices of meat
(sausage, pepperoni, hamburger, and none) and two types of cheese (regular or double). How many different styles of pizza can be ordered?
MATH Prob. -
There are 4 sizes, 3 crusts, 4 meats and 2 cheeses.
Since these are independent choices, the number of styles of pizza would the the product of the possible choices.
