3. This statement is true.
Since the CDF measures the cumulative values of the PDF, the value of CDF is always greater than the value of PDF for a discrete random variable. So, the statement is true.
4. The expected value and variance of a Poisson distributed random variable is equal. So, if the expected value of a Poisson variable is 74.1 then the variance of that variable would also be 74.1.
