Homework Help: Statistics

Posted by Christine on Wednesday, May 14, 2008 at 5:16pm.

A student is taking a multiple-choice exam with 16 questions. Each question has five alternatives. If the student guesses on 12 of the questions, what is the probability she will guess at least 8 correct? Assume all of the alternatives are equally likely for each question on which the student guesses.

I thought this was pretty easy but I cannot figure it out!
