Suppose a shipment of 140 electronic components contains 4 defective components. To determine whether the shipment should be accepted, a quality control engineer randomly selects 4 of the components and test them. If 1 or more of the components is defective, the shipment is rejected. what is the probability that the shipment rejected?

A box contains 10 items, of which 3 are defective and 7 are non-defective. Two items are randomly selected, one at a time, with replacement, and x is the number of defective items in the sample. To look up the probability of a defective item being drawn from the box, using a binomial probability table, what would be the values of n, x and p to look up?

A factory produces components of which 1% are defective. The components are packed in boxes of 10. A box is selected by random. a) Find the probability that there are at most 2 defective components in the box. b) Use a suitable approximation to find the probability of having at most 3 defective (inclusive 3 cases) components out of 250.

Suppose that in a batch of 500 components, 20 are defective and the rest are good. A sample of 10 components is selected at random with replacement, and tested. Let X denote the number of defectives in the sample. a. What is the PMF of X? State the distribution, its parameters, and give the equation for its PMF with the correct parameters. b. What is the probability that the sample contains at least one defective component?
