Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. 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 seven. 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)...

Question Help In a recent year, a hospital had 4145 births. Find the mean number of births per day, then use that result and the Poisson distribution to find the probability that in a day, there are 13 births.
