a) How many positive three-digit integers are multiples of 7? (b) What is the probability that a randomly chosen positive three-digit integer is a multiple of 7? (c) What is the probability that a randomly chosen positive three-digit integer is a multiple of 6? Suppose that on a true/false exam you have no idea at all about the answers to three questions. You choose answers randomly and therefore have a 50–50 chance of being correct on any one question. Let CCW indicate that you were correct on the first two questions and wrong on the third, let WCW indicate that you were wrong on the first and third questions and correct on the second, and so forth. (a) List the elements in the sample space whose outcomes are all possible sequences of correct and incorrect responses on your part. (b) Write each of the following events as a set, in set-roster notation, and find its probability. (i) The event that exactly one answer is correct. set = .........?probability…
