A population of semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform to a thickness specification, with the results shown in the following table. A wafer is chosen at random from the population. A. Given that the wafer is from Lot B, what is the probability that it is conforming? B. Given that the wafer is nonconforming, what is the probability that it from Lot B?
