Under what circumstances should the hypergeometric distribution be used instead of the binomial distribution?
Answer to relevant QuestionsUsing the hypergeometric distribution, with N = 4, n = 2, and s = 3, determine the following: a. P(x = 0) b. P(x = 1) c. P(x = 2) For a discrete random variable that is Poisson distributed with (= 2.0, determine the following: a. P(x = 0) b. P(x = 1) c. P(x ≤ 3) d. P(x ≥ 2) Over the past year, a university’s computer system has been struck by a virus at an average rate of 0.4 viruses per week.
