यदि \(A=\{1,2\}\) और \(B=\{x,y,z\}\) हैं, तो (A) से (B) तक कुल कितने संबंध हो सकते हैं?
If \(A=\{1,2\}\) and \(B=\{x,y,z\}\), how many relations can exist from (A) to (B)?
Explanation opens after your attempt
Correct Answer
B. \(2^6\)
Concept
Here (n\(A\times B\)=2\cdot3=6), so the number of relations is \(2^6\). Count the pairs in \(A\times B\) first.
Why this answer is correct
The correct answer is B. \(2^6\). Here (n\(A\times B\)=2\cdot3=6), so the number of relations is \(2^6\). Count the pairs in \(A\times B\) first.
Exam Tip
(n\(A\times B\)=2\cdot3=6), इसलिए संबंधों की संख्या \(2^6\) है। पहले \(A\times B\) के pairs गिनें।
