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
Correct Answer

A. (0)

Step 1

Concept

When (A=U), the complement is empty. Therefore (A') has (0) elements.

Step 2

Why this answer is correct

The correct answer is A. (0). When (A=U), the complement is empty. Therefore (A') has (0) elements.

Step 3

Exam Tip

जब (A=U) हो तो पूरक रिक्त होता है। इसलिए (A') में (0) तत्व हैं।
