यदि \(A=\{1,2,3\}\) और \(B=\{4,5\}\), तो \(A\times B\) के कितने उपसमुच्चय ठीक (1) अवयव वाले संबंध हैं?
If \(A=\{1,2,3\}\) and \(B=\{4,5\}\), how many one-element relations are subsets of \(A\times B\)?
Explanation opens after your attempt
B. (6)
Concept
\(|A\times B|=6\), so there are (6) ways to choose a one-element relation. A singleton relation is just one ordered pair.
Why this answer is correct
The correct answer is B. (6). \(|A\times B|=6\), so there are (6) ways to choose a one-element relation. A singleton relation is just one ordered pair.
Exam Tip
\(|A\times B|=6\), इसलिए (1) अवयव वाला संबंध चुनने के (6) तरीके हैं। एकल संबंध सीधे एक क्रमित युग्म होता है।
