A type of multifunction printer produced by ABC Company was found to be defective (D). There are three factories (A, B, C) manufacturing this product (35% from factory A, 35% from factory B, and 30% from factory C). A manager is responsible for investigating the source of found defects. So far, the manager knows the following information: P(D | A) = 0.018, P(D | B) = 0.010, P(D | C) = 0.022. The manager would like to answer the following questions: If a randomly selected printer is defective, what is the probability that the printer was manufactured in factory A? Also, if a randomly selected printer is defective, what is the probability that the printer was manufactured in factory B?
