यदि \(A=\{1,2,3\}\) है, तो (A) पर कुल कितने संबंध संभव हैं?
If \(A=\{1,2,3\}\), how many relations are possible on (A)?
Explanation opens after your attempt
C. \(2^9\)
Concept
A relation on (A) is a subset of \(A\times A\), and \(|A\times A|=9\). Hence total relations are \(2^9\).
Why this answer is correct
The correct answer is C. \(2^9\). A relation on (A) is a subset of \(A\times A\), and \(|A\times A|=9\). Hence total relations are \(2^9\).
Exam Tip
(A) पर संबंध \(A\times A\) का उपसमुच्चय होता है और \(|A\times A|=9\)। इसलिए कुल संबंध \(2^9\) हैं।
