The number of ways Patricia can choose 4 pizza toppings from a menu of 15 toppings can be calculated using the combination formula:
C(n, k) = n! / (k! * (n - k)!)
Where n is the total number of toppings on the menu (15) and k is the number of toppings Patricia wants to choose (4).
C(15, 4) = 15! / (4! * (15 - 4)!)
C(15, 4) = 15! / (4! * 11!)
C(15, 4) = (15 * 14 * 13 * 12) / (4 * 3 * 2 * 1)
C(15, 4) = 32760
Therefore, there are 32,760 ways Patricia can choose 4 pizza toppings from a menu of 15 toppings if each topping can only be chosen once.
