A student is taking a multiple-choice exam in which each question has

five

choices. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place five balls (marked A,B,C,D,andE) into a box. She randomly selects one ball for each question and replaces the ball in the box. The marking on the ball will determine her answer to the question. There are

four multiple-choice questions on the exam. Complete parts (a) through (d) below.
