JEE Mains · Maths · STD 11 - 1. set theory
If \(A=\{x \in R:|x|<2\}\) and \(B=\{x \in R:|x-2| \geq 3\}\) then
- A \(A \cup B=R-(2,5)\)
- B \(A \cap B=(-2,-1)\)
- C \(B-A=R-(-2,5)\)
- D \(A-B=[-1,2)\)
Answer & Solution
Correct Answer
(C) \(B-A=R-(-2,5)\)
Step-by-step Solution
Detailed explanation
\(A: x \in(-2,2) ; B: x \in(-\infty,-1] \cup[5, \infty)\) \(\Rightarrow B-A=R-(-2,5)\)
