1. A certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player (so the event B is contained in A). Sup- pose that P(A) = .6 and P(B) = .05. What is P1B 0 A 2?
2. In Exercise 15, Ai = {awarded project i}, for i = 1, 2, 3. Use the probabilities given there to compute the following probabilities:
a. P1A2 0 A1 2
b. P1A2 ¨ A3 0 A1 2
c. P1A2 ´ A3 0 A12
d. P1A1 ¨ A2 ¨ A3 0 A1 ´A2´ A3 2
Express in words the probability you have calculated.
