A local pizzeria offers 11 toppings for their pizzas and you can choose any 4 of them for one fixed price. How many different types of pizzas can you order with 4 toppings?

Respuesta :

first slot, 11 options
2nd is 10 (1 less than 1st slot)
3rd is 9
4th is 8


11*10*9*8=7920 different pizzas (assuming you can't order all 1 topping)
