In how many ways can a student check four correct answer.
~~~~~~~~~~~~~~~

As it is worded, printed, posted and presented, this problem is INCOMPLETE.

To be complete, it MUST say how many of 4 possible answers in each question are correct.

The problem is poorly worded -- or perhaps the wording was intended to mislead the reader.

In fact, with the wording as it is, the number of answer choices on each question is irrelevant; the question only asks in how many ways a student can get 4 of the 15 questions right. The answer is simply "15 choose 4".

ANSWER: C(15,4) = 1365
