A population of 596 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 answer as a fraction or a decimal, rounded to four decimal places. Lot Conforming Nonconforming A 83 11 B 160 32 C 264 46 Given that the wafer is nonconforming, what is the probability that it is from Lot C
