ANSWER.  %28847%2B804%29%2F3228 = 0.51  (rounded).


Find the numbers 847, 804 and 3228 in the Table and think WHY I choose and used these numbers.


These values are added in the formula because the two sets of interest are disjoint.

Solved.

Add up the totals for the age groups "18-28" and "29-38" which represents everyone under 39 years old.
847+804 = 1651

There are 1651 people younger than 39 years of age.

This is out of the 3228 people total in the bottom right corner.

1651/3228 = 0.511462 approximately which rounds to 0.51
This is the approximate probability of selecting a voter under 39 years old.
