Give examples of values of n and p, both non-zero, for a binomial random variable X. Use either the binomial probability formula or the binomial probability cumulative distribution tables provided in class to calculate:
a) $P (X = x_{0})$ where $x_{0}$ is an integer of your own choice satisfying

$0 < x_{0} < n$ .
b) $P (X > x_{0})$
