Question

CONDITIONAL AND MARGINAL PROBABILITY - Statistics and probability }

1) In a plant, complex components are assembled on two different assembly lines, A and B. Line A uses older equipment than B, so it is a bit slower and less reliable. Suppose that on a given day line A assembles 8 components, of which 2 have been identified as defective (D) and 6 as non-defective (ND), while B has produced 1 defective and 9 non-defective components. .

a) What is the probability that, when selecting a component at random, a defective one will come out?

b) If the selected component is defective, what is the probability that it has left line A? What is the probability that it came out of line B?
