A group of parts were manufactured on two machines; machine A and machine B. 55% of the parts were manufactured on machine A, 45% on machine B. Machine A produces 20% defective parts (D) and 80% non- defective parts (N). Machine B produces 10% defective parts. This data is summarized in the following probability tree. Calculate the probability that a randomly selected part was manufactured on machine A and is not defective.
