The Denver post reported that recent audios of LA 911 calls showed that 85% were it emergencies. Suppose 911 operators in LA have received 2 calls. (a) What is the probability that all two calls are, in fact, emergencies? (Round your answer to three decimal places.) (b) What is the probability that one or more calls are not emergencies? (Round your answer to three decimal places.) (c) What is the smallest number of calls n that the 911 operators need to answer to be at least 96% (or more) sure that at least one call is, in fact, an emergency? (Enter your answer as a whole numbe
