Question

at a factory that produces pistons for cars machine 1 produces 616 satisfactory pistons and 84 unsatisfactory Pistons today. machine 2 produced 414 satisfactory pistons and 276 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 from machine 1 is unsatisfactory and the piston from machine 2 is satisfactory do not round your answer decimal please​

Answer 1

The probability of getting unsatisfactory piston of machine 1 and satisfactory machine of piston 2 is 0.072

Explanation:

p(E) = p(unsatisfactory Pistons of machine 1) = 84/700

p(F) = p(Satisfactory Pistons of machine 2) = 414/690

p(E and F) =

p(unsatisfactory piston of machine 1 and satisfactory machine of piston 2)

p(E and F) = p(E) . p(F)

= 84/700 . 414/690

= 0.072
