Question

Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. Find the probability that the screws drawn will be nondefective in drawing (a) with replacement, (b) without replacement. find the probability of E: At least 1 defective (i) directly, (ii) by using complements; in both cases (a) and (b).
