यदि \(A=\{1,2\}\) और \(R=A\times A\) है, तो (R) symmetric है या नहीं?
If \(A=\{1,2\}\) and \(R=A\times A\), is (R) symmetric?
Explanation opens after your attempt
Correct Answer
A. हाँYes
Concept
In \(A\times A\), every pair has its reverse pair too. Hence the universal relation is symmetric.
Why this answer is correct
The correct answer is A. हाँ / Yes. In \(A\times A\), every pair has its reverse pair too. Hence the universal relation is symmetric.
Exam Tip
\(A\times A\) में हर pair के साथ उसका reverse pair भी होता है। इसलिए universal relation symmetric है।
