A population of 600 semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform to a thickness specification. The following table presents the number of wafers in each category. A wafer is chosen at random from the population.
a. If the wafer is from Lot A, what is the probability that it is conforming?
b. If the wafer is conforming, what is the probability that it is from Lot A?
c. If the wafer is conforming, what is the probability that it is not from Lot C?
d. If the wafer is not from Lot C, what is the probability that it is conforming?
