यदि \(A=\{1,2,3\}\) और \(B=\{a,b\}\) हैं, तो (A) से (B) तक कुल कितने संबंध बन सकते हैं?
If \(A=\{1,2,3\}\) and \(B=\{a,b\}\), how many total relations can be formed from (A) to (B)?
Explanation opens after your attempt
Correct Answer
B. \(2^6\)
Concept
Since \(|A\times B|=3\times2=6\), the number of relations is \(2^6\). In exams, first find the number of elements in \(A\times B\).
Why this answer is correct
The correct answer is B. \(2^6\). Since \(|A\times B|=3\times2=6\), the number of relations is \(2^6\). In exams, first find the number of elements in \(A\times B\).
Exam Tip
क्योंकि \(|A\times B|=3\times2=6\), इसलिए संबंधों की संख्या \(2^6\) होगी। परीक्षा में पहले \(A\times B\) के अवयवों की संख्या निकालें।
