Chapter 5 2)A population of 621 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. Write your answers as a fraction in lowest terms. Lot Conforming Nonconforming A B C 85 168 261 (a) What is the probability that the wafer is from Lot C? 21 44 42 (b) What is the probability that the wafer is nonconforming? (c) What is the probability that the wafer is from Lot C and is nonconforming?
