WebSep 18, 2024 · Computing this probability mass function requires you to find the set S ( z) for each z in your support. The distribution has mean and variance: E ( Z) = ( n p) 2 V ( Z) = ( n p) 2 [ ( 1 − p + n p) 2 − ( n p) 2]. The distribution will be quite jagged, owing to the fact that it is the distribution of a product of discrete random variables.
