On \(A=\{1,2,3\}\), what is the correct property of \(R=\{(1,2),(2,1),(2,3),(3,2)\}\)?
Explanation opens after your attempt
Correct Answer
A. सममितSymmetric
Concept
For every ((a,b)), ((b,a)) is also present, so the relation is symmetric. For reflexivity, ((1,1),(2,2),(3,3)) are also needed.
Why this answer is correct
The correct answer is A. सममित / Symmetric. For every ((a,b)), ((b,a)) is also present, so the relation is symmetric. For reflexivity, ((1,1),(2,2),(3,3)) are also needed.
Exam Tip
हर ((a,b)) के साथ ((b,a)) भी है, इसलिए संबंध सममित है। प्रतिवर्ती होने के लिए ((1,1),(2,2),(3,3)) भी चाहिए।
