Read details carefully for questions in the following figure, the triangle represents teachers, the circle represents students and the rectangle represents actors.
Which number represents students who are also actors but not teachers?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 3
Students who are also actors lie where the circle and the rectangle overlap; “not teachers” leaves out the part inside the triangle. That is the region marked 3 (shaded below).
