Question

Maria's trattoria offers ham, green peppers, black olives, mushrooms, onions, and anchovies as toppings for the plain cheese base of its pizzas. how many different pizzas can be made?

Answer 1

Decide whether you want ham or no. you have 2 choices. regardless, next you choose green peppers or no. every choice has 2 answers (yes or no). and each decision leads to 2 more decisions for the next be topping. since there are 6 possible toppings there are 2^6 outcomes or 64 different pizzas you could order.

please ask if you need further information or clarification.
