 - The function $p(x | n, p)$ is the mass function. It is a function of $x$, the possible values of the random variable $X$. It is conditional on the **parameters** $n$ and $p$. Different values of these parameters specify different binomial distributions.
 - $x = 0, 1, \ldots, n$ indicates the **sample space**, that is, the possible values of the random variable.
