Suppose there are three rooms of individuals as follows: In Room 1 there are 5 math majors and 6 engineering majors; in Room 2 there are 4 math majors and 2 engineering majors, and in Room 3 there are 6 math majors and 3 engineering majors. Assume you randomly choose a room, each with probability 1/3, and then choose 3 persons, again with all choices occurring with equal probability. Suppose your selection consists of 3 engineering majors and no math majors.

Factories A, B and C produce computers. Factory A produces 4 times as many computers as factory C, and factory B produces 6 times as many computers as factory C. The probability that a computer produced by factory A is defective is 0.038, the probability that a computer produced by factory B is defective is 0.035, and the probability that a computer produced by factory C is defective is 0.047. A computer is selected at random and it is found to be defective. What is the probability it came from factory B? Answer:
