What is the total number of observations in that distribution?

Explanation:
Total observations come from adding up the counts in every category of the distribution. Each row tells how many observations fall into that category, so you sum all those numbers to get the overall sample size. In this distribution, those counts add up to twelve, which is why the total number of observations is twelve. For example, if the category counts were 2, 3, 4, and 3, their sum would be 12.
