Explanation:

The titles in the same row/column should describe different states. For example, if one category in the first column is "brown eyes" then the other category should be "not brown eyes". To fill in the numbers, look at the intersections of different categories in the Venn diagram. For example, in the Venn diagram there are 65 people in the "Junior" circle that aren't also in the "Boys" circle, so in the table you would put 65 in the "juniors" and "not boys" cell. For the totals, sum up the numbers in the respective row/column.
