Show answer & explanation
Correct answer: C
Goal: Find the number of writers who write both Fiction and Horror but do not write Thriller.
Reasoning: On the Venn diagram, the region that represents writers who write both Fiction and Horror but not Thriller is the lens-shaped overlap between the Fiction and Horror circles that lies outside the Thriller circle.
Locate the number in the overlap of Fiction and Horror excluding the central triple-overlap. The diagram shows this region labeled 8.
Do not include the central triple-overlap (writers of all three genres) or regions that include Thriller.
Answer: 8
