यदि \(A=\{1,2,3\}\) और \(B=\{4,5\}\) हों तो (A) से (B) तक कुल कितने संबंध बन सकते हैं?
If \(A=\{1,2,3\}\) and \(B=\{4,5\}\), how many total relations can be formed from (A) to (B)?
Explanation opens after your attempt
Correct Answer
C. (64)
Concept
Since (n\(A\times B\)=3\times 2=6), the number of relations is \(2^6=64\). In exams, first count the elements of \(A\times B\).
Why this answer is correct
The correct answer is C. (64). Since (n\(A\times B\)=3\times 2=6), the number of relations is \(2^6=64\). In exams, first count the elements of \(A\times B\).
Exam Tip
क्योंकि (n\(A\times B\)=3\times 2=6) और संबंधों की संख्या \(2^6=64\) होती है। परीक्षा में पहले \(A\times B\) के अवयव गिनें।
