Step 2 Now, use the data in the table to make a histogram of the probability distribution. 1 2 3 4 or more P(x) 0.46 0.33 0.17 0.03 0.01 Recall that the height of each bar in a histogram indicates the class frequency. So to construct the histogram, put the x values on the horizontal axis and the probabilities on the vertical discrete, each class mark will be centered over the x value. There are five classes in the table, so there are axis. Since the data are 6. X vertical bars on the histogram.
