A certain system can experience three types of defects. Let A,(i = 1,2,3) denote the event that the system has a defect of type 'i'. Suppose that P(A) = 0.12 P(A,) = 0.07 P(A,) = 0.05 P(A, U Az) = 0.13 P(A, U 4) = 0.14 P(A, U A,) = 0.10 P(4nA,04,) = 0.01 (a) What is the probability that the system does not have a type 1 defect? (b) What is the probability that the system has both type 1 and type 2 defects? (c) What is the probability that the system has both type 1 and type 2 defects but not a type 3 defect? (d) What is the probability that the system has exactly two of these defects?
