Answer:
455 possible ways
Step-by-step explanation:
We are told that 15 women are trying out for parts in a production of snow white.
Now, we want to find the number of ways that 3 women can be selected to play.
This is simply a combination question.
Thus;
Number of ways = C(15, 3) = 15!/((15 - 3)!(3!) = 15!/(12! × 3!) = (15 × 14 × 13 × 12!)(12! × 3 × 2 × 1)
12! will cancel out to give;
(15 × 14 × 13)/6 = 455
