किसी सर्वसमुच्चय (U) के लिए \(A\cap A'\) किसके बराबर है?
For a universal set (U), \(A\cap A'\) is equal to which set?
Explanation opens after your attempt
D. \( \varnothing \)
Concept
No element can be in both (A) and (A') at the same time. Therefore the intersection is \(\varnothing\).
Why this answer is correct
The correct answer is D. \( \varnothing \). No element can be in both (A) and (A') at the same time. Therefore the intersection is \(\varnothing\).
Exam Tip
कोई अवयव एक साथ (A) और (A') दोनों में नहीं हो सकता। इसलिए प्रतिच्छेद \(\varnothing\) है।
