Read It . . . . . . . .... d) Repeat part (b) for a community of 750 people. (Round your answers to four decimal places.) Frequency of births (or deaths) is a rare occurrence. It is reasonable to assume the events are dependent. Frequency of births (or deaths) is a rare occurrence. It is reasonable to assume the events are independent. O Frequency of births (or deaths) is a common occurrence. It is reasonable to assume the events are dependent. Frequency of births (or deaths) is a common occurrence. It is reasonable to assume the events are independent. A television program reported that the U.S. (annual) birth rate is about 22 per 1000 people, and the death rate is about 8 per 1000 people. . . . . (a) Explain why the Poisson probability distribution would be a good choice for the random variable r = number of births (or deaths) for a community of a given population size? c) Repeat part (b) for a community of 1500 people. You will need to use a calculator to compute P(4 births) and P(18 births). (Round your answers to four decimal places.) (b) In a community of 1000 people, what is the (annual) probability of 4 births? What is the probability of 4 deaths? What is the probability of 18 births? 18 deaths? (Round your answers to for
