In a certain factory, machines D, E and F all produce computer chips of the same type. Of their production, machines D, E and F, respectively produce 2%, 3% and 1% defective chips. Machine D produces 30% of the output of the factory, machine E 25% and machine F the rest. If one chip is selected at random from the output of the factory, find the probability that it is defective. If it is defective, find the probability that it was manufactured on machine F.
