A certain system can experience three different types of defects. Let A (i = 1,2,3) denote the event that the system has a defect of type i. Suppose that (a) Find the probability that the system has exactly 2 of the 3 types of defects. (b) Find the probability that the system has a type 1 defect given that it does not have a type 2 defect and does not have a type 3 defect.
