In a manufacturing plant, machine A produces 10% of a certain product, machine B produces 40% of this product, and machine C produces 50% of this product. Five percent of machine A products are defective, 12% of machine B products are defective, and 8% of machine C products are defective. The company inspector has just sampled a product from this plant and has found 1000 to be defective. Determine the revised probabilities that the sampled product was produced by machine A, machine B, or machine C and specify the number of defectives to be allocated to each machine.
