In a Venn diagram of two sets A and B, what does the region A−B represent?
Answer and explanation
Correct answer: Elements that are in A but not in B
The difference A−B, also written A\B, contains every element that belongs to A but does not belong to B. In the Venn diagram it is the portion of circle A lying outside the overlap with circle B. Option B describes B−A, option C describes A∩B, and option D describes the region outside A∪B. Hence option A is correct.
