यदि \(U=\{1,2,3,4,5,6,7,8\}\) और \(A^c={2,4,6,8}\) है, तो \(A\cap A^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\) and \(A^c={2,4,6,8}\), what is \(A\cap A^c\)?
Explanation opens after your attempt
A. \(\varnothing\)empty set
Concept
(A) and \(A^c\) have no common element. Therefore \(A\cap A^c=\varnothing\) directly.
Why this answer is correct
The correct answer is A. \(\varnothing\) / empty set. (A) and \(A^c\) have no common element. Therefore \(A\cap A^c=\varnothing\) directly.
Exam Tip
(A) और \(A^c\) में कोई साझा तत्व नहीं होता। इसलिए \(A\cap A^c=\varnothing\) सीधे मिलता है।
