There are 70 different types of pizzas could be ordered
A permutation is an act of arranging the objects or numbers in order.
Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter
Given,
Number of options on crust=2
Number of options on topping= 7
Number of options on size= 5
Therefore for each type of crust there are 7 different topping, for each toppings there are 5 different sizes
The total number ways of ordering pizza=2×7×5=70
Hence, there are 70 different types of pizzas could be ordered
