At a factory that produces pistons for cars, Machine 1 produced satisfactory pistons and unsatisfactory pistons today. Machine 2 produced satisfactory pistons and 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 ?

I suspect that there's supposed to be a number before each "satisfactory" and each "unsatisfactory", and I'm pretty sure that none of them is there. The question, exactly as it's written, can't be answered.
