The problem is:

Tree manufacturing plants produce similar products. The fist one produce 15%, the second one 55% and third the rest of the whole production. Plan 1 produces 3% defective products, plan 2 produces 4% and plant 3 produces 5% defective products. A product is selected at random.

a) What is the probability that it will not be defective? What is the probability it came from the second plant?

b) Find the probability of the event that the selected product is defective.

Thank You,
