यदि \(U=\{a,b,c,d,e\}\) और \(A^c={b,e}\) है, तो \(A\cup A^c\) क्या होगा?
If \(U=\{a,b,c,d,e\}\) and \(A^c={b,e}\), what is \(A\cup A^c\)?
Explanation opens after your attempt
A. (U)
Concept
\(A\cup A^c\) is always the whole (U). So it is not necessary to find (A).
Why this answer is correct
The correct answer is A. (U). \(A\cup A^c\) is always the whole (U). So it is not necessary to find (A).
Exam Tip
\(A\cup A^c\) हमेशा पूरा (U) होता है। इसलिए (A) निकालना जरूरी नहीं है।
