Determining the poisson random variable

Reference no: EM131001072

(i) Obtain the complete pdf, f (x), for the binomial random variable with n = 10, p = 0.05, for x = 0, 1, ..., 10, and compare it to the corresponding pdf, f (x), for a Poisson variable with λ = 0.5.

(ii) Repeat (i) for n = 20,p = 0.5 for the binomial random variable, and λ = 10 for the Poisson random variable.
