A foreman for the injection-molding firm admits that on 46% of his shifts, he forgets to shut off injection machine on his line. This causes the machine to overheat, raising the probability that the defective molding will be produced throughout the early morning run from 2% to 18%. The plant manager randomly chooses a molding from the early morning run and discovers it is defective. Determine the probability that the foreman forgot to shut off the machine the previous night?
