Among 29- to 34-year-olds, 28% say they have called a talk show while under the influence of alcohol. Suppose seven 29- to 34-year-olds are selected at random. Complete parts (a through (d) below. (a) What is the probability that all seven have called a talk show while under the influence of alcohol? (Round to four decimal places as needed.) (b) What is the probability that at least one has not called a talk show while under the influence of alcohol? (Round to four decimal places as needed.) (c) What is the probability that none of the seven have called a talk show while under the influence of alcohol? (Round to four decimal places as needed.) (d) What is the probability that at least one has called a talk show while under the influence of alcohol?
