यदि \(A=\{1,2\}\) और \(B=\{a,b,c,d\}\) हैं, तो (A) से (B) तक कुल कितने संबंध हो सकते हैं?
If \(A=\{1,2\}\) and \(B=\{a,b,c,d\}\), how many relations can be formed from (A) to (B)?
Explanation opens after your attempt
Correct Answer
C. \(2^8\)
Concept
Here (n\(A\times B\)=2\cdot4=8), so the number of relations is \(2^8\). Find (n\(A\times B\)) first.
Why this answer is correct
The correct answer is C. \(2^8\). Here (n\(A\times B\)=2\cdot4=8), so the number of relations is \(2^8\). Find (n\(A\times B\)) first.
Exam Tip
(n\(A\times B\)=2\cdot4=8), इसलिए संबंधों की संख्या \(2^8\) है। पहले (n\(A\times B\)) निकालें।
