Question

You are ordering a 3 topping pizza, and there are 7 pizza toppings that you like from which you are choosing. You can use C(3, 7) to find out how many possible pizzas you could order.

Answer 1

it can't be C(3,7), the first number needs to be the larger number

so it should be C(7,3)

 which equals 7!/(3!(7−3)!)  = 35  possible pizzas 

Answer 2

This is false cant be used. Hope this helped.
