यदि \(A=\{x,y\}\) है, तो (A) पर सार्वत्रिक संबंध में कितने ordered pairs होंगे?
If \(A=\{x,y\}\), how many ordered pairs are in the universal relation on (A)?
Explanation opens after your attempt
C. (4)
Concept
A universal relation contains all pairs of \(A\times A\), and \(|A\times A|=2\times2=4\). In exams, treat universal relation as the complete Cartesian product.
Why this answer is correct
The correct answer is C. (4). A universal relation contains all pairs of \(A\times A\), and \(|A\times A|=2\times2=4\). In exams, treat universal relation as the complete Cartesian product.
Exam Tip
सार्वत्रिक संबंध \(A\times A\) के सभी युग्म रखता है और \(|A\times A|=2\times2=4\)। परीक्षा में universal relation को पूरा Cartesian product मानें।
