Aforeman for an injection-molding firm admits that on 9% of his shifts, he forgets to shut off the injection machine on his line. this causes the machine to overheat, increasing the probability that a defective molding will be produced during the early morning run from 1% to 19%.
let f = forgets to shut off the injection machine and d = defective. use a probability tree to answer the following questions: (round all answers to four decimals)a) whatâs the probability a molding from the early morning run is defective? b) the plant manager randomly selects a molding from the early morning run and discovers it is defective. what is the probability that the foreman forgot to shut off the machine the previous night?
