A restaurant offers four sizes of pizza, two types of crust, and eight topings. How many possible combinations of pizza with 4 toppings are there

Answer 1

The possible combinations of 4 toppings given that there are 8 to choose from is found using the combination equation 8C4 = 8!/(4!(8-4)!) = 70. Since there are 4 different sizes x 2 types of crust x 70 possible combinations of toppings, there are 560 possible combinations of pizza.
