Solving problem N3654 Bayesian probability theory

3654. From the first automatic machine, 18% of parts come to the assembly conveyor, from the 2nd and 3rd - 25% and 57% respectively. The probabilities of issuing defective parts are for each of them, respectively, 0.25%, 0.35% and 0.15%. Find the probability that the part arriving at the assembly will be defective, as well as the likelihood that it was made on the 1st, 2nd and 3rd automatic machine tools, provided that it turned out to be defective.
