Asked by Bridget
A student was totally unprepared for a multiple-choice test and had to absolutely guess the answer to every one of the 100 questions. About what score (percent) would you expect him to earn if there were four possible answers to every question?
I'm not sure where to start on this one. I know how to find the probability of one letter being the correct answer (1/4) but I do not know how to work through this type of problem.
Thanks
