Suppose a biology student is about to take an exam that is entirely multiple choice, where each question has 5 answer choices. This student only studied 60% of the material that is covered on this exam, so let us assume that there is a 60% chance that she knows the correct answer to any given question. If she does not know the answer, she will choose an answer at random. If the exam has a total of 40 questions on it, how many would you expect her to get wrong?
