How many ways can Karen choose 5

Question

pizza toppings from a menu of 12
toppings if each topping can only be chosen once?

Answer 1

The number of ways Karen can choose 5 pizza toppings from a menu of 12 toppings can be calculated using the combination formula.

C(n, r) = n! / (r!(n-r)!)

In this case, n=12 (total number of toppings) and r=5 (number of toppings to choose).

C(12, 5) = 12! / (5!(12-5)!)
C(12, 5) = 792

Therefore, there are 792 ways Karen can choose 5 pizza toppings from a menu of 12 toppings.
