Consider a Bernoulli trial where 
Suppose this Bernoulli trial is repeated times. (a) Plot the probability mass function for a Binomial random variable ,X , with 
(b) Plot the corresponding probability mass function for a Poisson random variable X 
(c) Compare 
as computed by both the Binomial and Poisson random variables. Is the Poisson random variable a good approximation for the Binomial random variable for this example?
