a. What is the difference between “variable” and “random variable”?
b. Give two real life examples, one would be appropriate for binomial distribution and the other
would for Poisson distribution.
c. Explain why binomial distribution is related to the selection of “with replacement” NOT
“without replacement”.
d. In what situation normal probability rule can be used to obtain binomial probability? How
would you evaluate the appropriateness of this rule?
