Answer:
191.4
Explanation:
Set E includes all the numbers in the first row. Set D includes all the numbers in the right-most column. (7.6 is included in both those sets, but should be added only once.)
Set E∪D is the sum of those numbers:
E∪D = 120.1 +25.7 +24.4 +7.6 +2.2 +0.8 +10.6 = 191.4
The set E∪D includes 191.4 million humans.
