(ii) Show that P(B) = P(B/A). P(A) + P(B/AC) P(AC) = P(A).
Two floppies are selected at random without replacement from a box containing 7 good and 3 defective floppies. Let A be the event that the first floppy drawn is defective, and let B be the event that the second floppy drawn is defective.
(i) Find the conditional probabilities P(B/A) and P(B/AC)
