Quality control: A population of 610 semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform to thickness specification, with the results shown in the following table. A wafer is chosen at random from the population. Write your answer as a fraction or a decimal, rounded to four decimal places. Lot A B C Conforming 93 164 266 Send data to Excel Nonconforming 21 39 27 4 (a) What is the probability that the wafer is from Lot C? (b) What is the probability that the wafer is conforming? (c) What is the probability that the wafer is from Lot C and is conforming? (d) Given that the wafer is from Lot C, what is the probability that it is conforming? (e) Given that the wafer is conforming, what is the probability that it is from Lot C? (f) Let E, be the event that the wafer comes from Lot C, and let E₂ be the event that the wafer is conforming. Are E, and E₂ independent?
