In a particular county, the average number of suicides reported each month is 2.75. Assume that the number of suicides follows a Poisson distribution. What is the probability that at least two (two or more) suicides will be reported in a given month? What is the probability that no suicides will be reported in a given month? Assume that the number of suicides follows a Poisson distribution. What is the variance of this distribution? What is the probability that at most two (two or fewer) suicides will be reported?
