If A and B are two overlapping circles in a Venn diagram, which part is A − B?
Answer and explanation
Correct answer: Part of A that is not in B
Set difference A−B means the elements that belong to A but do not belong to B. In the diagram, this is the portion of circle A outside the overlap with circle B. The common lens-shaped region is excluded because those elements are also in B. Therefore, only the non-overlapping part of A represents A−B.
