Question 773341: A teacher chooses 3 students from a group of 14 to explain their project. In how many ways can she choose 3 students? Answers are: a. 228 b. 364 c. 1082 or d. 2184. Answer by Edwin McCravy(20056) (Show Source):
Since the order in which they are chosen is not important, this
problem asks for the number of combinations (not permutations)
of 14 things taken 3 at a time.
14×13×12
C(14,3) = -------- = 364
3×2×1
