A manufacturing plant producing electric motors has two production lines. In a typical day, 85% of the motors are produced in la
ne I, 15% in lane II. Past quality control study shows the probability that a randomly selected motors be defective is 12% if produced by line I, and 4% if produced by line II. A randomly selected motor from this manufacturing plant is tested for possible defect. Find the probability that the selected motor is produced by line 1 if the test shows that the selected engine is defective.
