A lot of 100 items contains k defective items. m items are chosen at random and tested. What is the probability that r items are found defective
A batch of n = 50 items contains m = 10 defective items. Suppose k = 10 items are selected at random and tested. How many items, k, do we need to sample, in order to get at least one defective item, with probability greater than 0.5?

(10 points) A lot of 100 items contains k defective items. M (Ms100) items are chosen at random and tested (a) (2 pts) How many different ways can we choose M items from 100 items in the lot? (b) (4 pts) How many different ways that among the M items...
In a lot of 100 items, two items are randomly selected for testing, and the lot is rejected if either of the tested items is found defective. (a) Find the probability that a lot with k defective items is accepted. (b) Calculate this probability numerically when k = 10, 30, 50 and 70.
A batch of n = 60 items contains m = 15 defective items. Suppose k = 10 items are selected at random and tested. What is the probability that we find exactly five defective items?
We have a batch of 100 pieces of which 20 are defective. 10 pieces are chosen at random. a) In how many ways can the 10 pieces be chosen? b) In how many ways can we choose 2 defective pieces and 8 good ones?
Paragraph 2-114. A lot of 100 semiconductor chips contains 10 that are defective. (a) Two are selected, at random, without replacement, from the lot. Determine the probability that the second chip selected is defective (b) Three are selêcted, at random, without replacement, from the lot. Determine the probability that all are defective.
A parking lot contains 100 cars, k of which happen to be lemons. We select m of these cars at random and take them for a test drive. Find the probability that n of the cars tested turn out to be lemons.
7. A lot of 100 semiconductor chips contains 10 that are defective. Three are selected, at random, without replacement, from the lot. (a) Determine the probability that the first chip selected is defective (b) Determine the probability that the second chip selected is defective. (c) Determine the probability that all three chips selected are defective. (d) Given that the second chip selected is defective, determine the (conditional) probability that all three chips selected are defective.
7) A lot of 100 semiconductor chips contains 20 that are defective. Two chips are selected at random, without replacement, from the lot. (a) What is the probability that the first one selected is defective? (b) What is the probability that the second one selected is defective given that the first one was defective? (c) What is the probability that both are defective?
