यदि \(U=\{1,2,3,4,5\}\) और \(A^c={2,5}\) है, तो \(A\cap A^c\) क्या होगा?
If \(U=\{1,2,3,4,5\}\) and \(A^c={2,5}\), what is \(A\cap A^c\)?
Explanation opens after your attempt
A. \(\varnothing\)empty set
Concept
For any (A), \(A\cap A^c=\varnothing\). Here there is no need to find (A) first.
Why this answer is correct
The correct answer is A. \(\varnothing\) / empty set. For any (A), \(A\cap A^c=\varnothing\). Here there is no need to find (A) first.
Exam Tip
किसी भी (A) के लिए \(A\cap A^c=\varnothing\) होता है। यहां (A) निकालने की भी जरूरत नहीं है।
