What type of data distribution is shown on the graph? A bar graph has x on the x-axis, from 0 to 4, and P x (x) on the y-axis, from 0 to 0.5 in 0.1 increments. The probability of 0 is 0.01, the probability of 1 is 0.25, the probability of 2 is 0.3, the probability of 3, is 0.4, and the probability of 4 is 0.02.
