Rather, it represents the average group size over the last 50 tables. The ty distribution is the of a discrete probability distribution does not have to equal one of the values average of the outcome for the random variables (2, 3, 4, 5, or 6 in this case). s of the random We could have also directly calculated the mean by using Formula 5.1: n the distribution
