Suppose X is distributed binomially, i.e. X ~ B(10, 0.1). Then, you'll want to calculate P(X = 0), P(X = 1), P(X = 2), ... , P(x = 10). For your axes, you'll have n (i.e. 0, 1, 2, ..., 10) on the horizontal axis, and you'll have the probability p for each P(X = n) along the vertical axis. The result might look something like this:
