In a factory, only two machines, A and B, manufacture washers. Neither machine is perfect: machine A produces defective washers 17% of the time, while machine B produces defectives 10% of the time. Machine B is more efficient than machine A and accounts for 70% of the total output of washers. For purposes of quality control, a sample of washers is taken and examined for defectives. Compute the probability that a randomly chosen washer found to be defective was manufactured by machine B. Round your answer to two decimal places. (If necessary, consult a list of formulas.) a 5 ?
