यदि \(U=\{1,2,3,4,5\}\) और \(A=\{1,2,3,4,5\}\) है तो (A') में कितने तत्व हैं?
If \(U=\{1,2,3,4,5\}\) and \(A=\{1,2,3,4,5\}\), how many elements are in (A')?
Explanation opens after your attempt
A. (0)
Concept
When (A=U), the complement is empty. Therefore (A') has (0) elements.
Why this answer is correct
The correct answer is A. (0). When (A=U), the complement is empty. Therefore (A') has (0) elements.
Exam Tip
जब (A=U) हो तो पूरक रिक्त होता है। इसलिए (A') में (0) तत्व हैं।
