Graph alt text 1

Bar graph of the probability function, with values of X (0, 1, 2, 3) along the horizontal (x) axis and probabilities (0.0, 0.1, 0.2, 0.3, 0.4) along the vertical (y) axis. Probabilities are shown as discrete columns at each value of X, such that there is a vertical line at X = 0 with height of 0.1, a line at X = 1 with height of 0.2, a line at X = 2 with height of 0.4, and a line at X = 3 with height 0.3. Expected value E(x) is shown by an arrow on the horizontal scale at X = 1.9.
