At a factory that produces pistons for cars, Machine 1 produced 273 satisfactory pistons and unsatisfactory 117 pistons today. Machine 2 produced 350 satisfactory pistons and 150 unsatisfactory pistons today. Suppose that one piston from Machine 1 and one piston from Machine 2 are chosen at random from today's batch. What is the probability that the piston chosen from Machine 1 is unsatisfactory and the piston chosen from Machine 2 is satisfactory ?
