Find C(n,r) where: C(n,r) = n! / ( r! (n - r)! ) n = (set) r = (subset)
Answer: C(n,r) = C(12,5) = 12! / (5! (12 - 5)!) = 792
The combination 12 C 5 calculates the number of ways to choose 5 items from 12. Using the combination formula, the answer is 792. This means there are 792 different ways to choose 5 items from a set of 12.
