Quality control: A population of 599 semiconductor wafers contains waters from three lots. The waters are categorized by it and by whether they conform to a thickness specification, with the results shown in the following table. A wafer e chosen at random from the population. Write your answer as a fraction or a decimal, rounded to four decimal places. Lot Conforming Nonconforting A 89 13 167 35 с 254 41 B Send data to Excel (a) What is the probability that the wafer is from Lot C? (b) What is the probability that the water is nonconforming? (c) What is the probability that the water is from Lot C and is nonconforming? (d) Given that the wafer is from Lot C, what is the probability that it is nonconforming? (e) Given that the wafer is nonconforming, what is the probability that it is from LOC? (Let E, be the event that the wafer comes from Lot C, and let E, be the event that the wafer is nonconforming. Are Ej and E independent?
