2. You are taking a 33 question multiple choice test, each question with 4 choices. Assume that getting 23 questions or more, correct, will result in a passing grade on the test. Complete parts (a), (b), and (c).
(a) If you randomly guess on a single question, what is the probability that you will get that question correct?
(b) If you randomly guess on all 33 questions, what is the probability that you will pass?
(c) About what number of questions would you expect to get correct, randomly guessing on all 33 questions?

Suppose you are taking an exam that only includes 80 multiple choice questions. Each question has five possible choices and only one of them is correct answer per question. Questions are not related to the material you know, so you guess the answer randomly in the order of questions written and independently. The probability that less than five questions are needed to mark the three correct answers is
