If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of births per minute in a country in a recent year was about three. Find the probability that the number of births in any given minute is (a) exactly five, (b) at least five, and (c) more than five. (a) P(exactly five)- Round to four decimal places as needed.) (b) P(at least five) Round to four decimal places as needed.) (c) P(more than five) Round to four decimal places as needed.) Which of the events are unusual? Select all that apply. A. The event in part (a) is unusual. □ B. The event in part (b) is unusual. C. The event in part (c) is unusual D. None of the events are unusual.
