यदि (n(A)=4) और (n(B)=5) है, तो (A) से (B) तक कुल कितने संबंध संभव हैं?
If (n(A)=4) and (n(B)=5), how many relations from (A) to (B) are possible?
Explanation opens after your attempt
Correct Answer
B. \(2^{20}\)
Concept
A relation is any subset of \(A\times B\), and (n\(A\times B\)=20). Hence the number of relations is \(2^{20}\).
Why this answer is correct
The correct answer is B. \(2^{20}\). A relation is any subset of \(A\times B\), and (n\(A\times B\)=20). Hence the number of relations is \(2^{20}\).
Exam Tip
संबंध \(A\times B\) का कोई भी उपसमुच्चय होता है और (n\(A\times B\)=20)। इसलिए कुल संबंधों की संख्या \(2^{20}\) है।
