यदि \(A=\{1,2,3,4\}\) पर एक तुल्य संबंध के वर्ग ({1,4}) और ({2,3}) हैं, तो (R) में कुल कितने युग्म होंगे?
If an equivalence relation on \(A=\{1,2,3,4\}\) has classes ({1,4}) and ({2,3}), how many ordered pairs are in (R)?
Explanation opens after your attempt
A. (8)
Concept
All ordered pairs within each class are included. The number is \(2^2+2^2=8\).
Why this answer is correct
The correct answer is A. (8). All ordered pairs within each class are included. The number is \(2^2+2^2=8\).
Exam Tip
प्रत्येक वर्ग के भीतर सभी क्रमित युग्म आते हैं। संख्या \(2^2+2^2=8\) है।
