3. You are in a game show in which you're asked a sequence of true/false questions. If you answer two of them wrong, you're out!! Unfortunately, you have no idea what the answers are, so you guess randomly each time, and you have a chance of guessing the correct answer. Let A3 be the event that your first wrong answer is to the third question you are asked. Let B4 be the event that your second wrong answer is to the fourth question you are asked. (a) Compute Pr[A3]. (b) Compute Pr[A3B4]. (c) Compute Pr[B4].
