Question

A university cafeteria offers 4 flavors of pizza – pepperoni, chicken, Hawaiian and vegetarian. If a customer has an option to add, extra cheese, mushrooms, or both to any kind of pizza, how many different pizza varieties are available?

Answer 1

There are 4 flavours of pizza, and technically, 4 different extra toppings as well (nothing, cheese, mushrooms or both). If you have 4 possible toppings and 4 different flavours, you’d simply do 4 x 4 = 16. So, there are 16 different pizza varieties.
