Suppose that three microchips in a production run of thirty are defective. A sample of five is to be selected to be checked for defects. (a) How many different samples of five can be chosen from the production run of thirty? MIT NO (b) How many samples will contain at least one defective chip? The set of samples that do not contain any defective chips and the set of samples that contain at least one defective chip are ---Select-- sets. So, the number of samples with at least one defective chip (c) What is the probability (as a percent) that a randomly chosen sample of five contains at least one defective chip?
