At a factory that produces pistons for cars, Machine 1 produced 343 satisfactory pistons and 147 unsatisfactory pistons today. Machine 2 produced 280 satisfactory pistons and 120 unsatisfactory pistons today. Suppose that one piston from Machine 1 and one piston from Machine 2 are chosen at random from today's batch. How do I find the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory ?
Do not round the answer.
