1.	A – B, A ∩ B and B – A are mutually disjoint sets or not.(a) True(b) FalseI got this question in semester exam.This intriguing question comes from Operation on Sets-2 in section Sets of Mathematics – Class 11
Answer» CORRECT choice is (a) True For explanation: A – B, A ∩ B and B – A does not have any common region so the INTERSECTION of any two of them is null SET. So, they are said to be mutually disjoint.
