Answer:
B. 455
Step-by-step explanation:
The order in which the toppings are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this question:
3 toppings from a set of 15. So
![C_{15,3} = \frac{15!}{3!(15-3)!} = 455](https://tex.z-dn.net/?f=C_%7B15%2C3%7D%20%3D%20%5Cfrac%7B15%21%7D%7B3%21%2815-3%29%21%7D%20%3D%20455)
455 3-topping sundaes can be made.
