At a factory that produces pistons for cars, Machine 1 produced 126 satisfactory pistons and 84 unsatisfactory pistons today. Machine 2 produced 180 satisfactory pistons and 120 unsatisfactory pistons today. Suppose that one position from Machine 1 and one pistons from Machine 2 are chosen at random from today’s batch. What is the probability that the pistons chosen from Machine 1 is satisfactory and the pistons chosen from Machine 2 is unsatisfactory?

Step 1
- Machine 1: total pistons = 126 satisfactory + 84 unsatisfactory = 210. - Machine 2: total pistons = 180 satisfactory + 120 unsatisfactory = 300. Show more…

At a factory that produces pistons for cars, Machine 1 produced 546 satisfactory pistons and 364 unsatisfactory pistons today. Machine 2 produced 900 satisfactory pistons and 100 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 satisfactory and the piston chosen from Machine 2 is unsatisfactory ?
