Question 577964: A student is asked to answer 7 out of 12 questions on an exam.
(a) Classify the problem as a permutation, a combination, or neither
Answer by dfrazzetto(283) (Show Source):
You can put this solution on YOUR website! It is a combination, since order does not matter.
If the student answers 1,2,3,4,5,6,7 versus 5,6,7,1,2,3,4, the end result is the same questions answered
