Sorry for asking, but I'm confused...
In your example, 1 is just a person who answers yes to question 2. But we are looking for both questions, so we have to include the 3 persons who answer yes to question 1 and the 1 person who answer yes to question 2. So, it should be 1+3=4. Then the number of people who answer no to both questions would be: 12-4=8
I remember this question from the OG 11
, and I know the OA is E. But still..
Who is John Galt?
