At the factory which produces pistons for cars, Machine 1 produced 248 satisfactory pistons and 62 unsatisfactory pistons today. Machine 2 produced 320 satisfactory pistons as well as 80 unsatisfactory pistons today. Assume that one piston from Machine 1 and one piston from Machine 2 are selected at random from today's batch.
