समुच्चय \(A=\{1,2\}\) पर कुल कितने संबंध बनाए जा सकते हैं?
How many total relations can be formed on the set \(A=\{1,2\}\)?
Explanation opens after your attempt
Correct Answer
D. (16)
Concept
A relation on (A) is a subset of \(A\times A\), and \(|A\times A|=4\), so total relations are \(2^4=16\). Remember subset counting for exams.
Why this answer is correct
The correct answer is D. (16). A relation on (A) is a subset of \(A\times A\), and \(|A\times A|=4\), so total relations are \(2^4=16\). Remember subset counting for exams.
Exam Tip
(A) पर संबंध \(A\times A\) का उपसमुच्चय होता है और \(|A\times A|=4\), इसलिए कुल संबंध \(2^4=16\) हैं। परीक्षा में उपसमुच्चयों की संख्या याद रखें।
