At a factory that produces pistons for cars, Machine 1 produced 261 satisfactory pistons and 29 unsatisfactory pistons today. Machine 2 produced 240 satisfactory pistons and 160 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 ? Do not round your answer. (If necessary, consult a list of formulas.) X 5
