Webchapter 3: discrete random variables and probability distributions 4 A probability histogram functions similarly to a line graph, but is a histogram, with bins centered on x of length 1 (usually) and with height p(x). Example 3 A fair coin is flipped; X(H) = 1 and X(T) = 0. Find the pmf of X, p(x). Visualize p(x) with a line graph.
