Factories A and B produce computers. Factory A produces 3 times as many computers as factory B. The probability that an item produced by factory A is defective is 0.037 and the probability that an item produced by factory B is defective is 0.05.
A computer is selected at random and it is found to be defective. What is the probability it came from factory A?
