A student is asked to answer 12 out of 14 questions on an exam. In how many ways can she select the questions to be answered?
============
She can leave out 2 questions.
The 1st is 1 of 14, then 1 of 13.
14*13 = 182
-----
Not doing question A and B is the same as not doing B and A --> 182/2 = 91 ways.

Using combination thats 14C12=14!/(14-12)!12!=91
