8. Suppose X has a binomial-(100, 1/50) distribution and Y has a Poisson
distribution with parameter λ?
(a) Compute P{X = k}.
(b) Compute P{Y = k}.
(c) What should be so that P{X = k} ≈ P{Y = k}?
(d) Compute P{X = k} and P{Y = k} for k = 0, 1, 2. Does the Poisson
distribution with your choice of λ appear to be a good approximation
of the binomial distribution for those three cases?
