यदि \(U=\{2,4,6,8\}\) और (A=U) है, तो \(A^c\) क्या होगा?
If \(U=\{2,4,6,8\}\) and (A=U), what is \(A^c\)?
Explanation opens after your attempt
A. \(\varnothing\)empty set
Concept
When (A=U), no element of (U) remains outside (A). Hence the complement is \(\varnothing\).
Why this answer is correct
The correct answer is A. \(\varnothing\) / empty set. When (A=U), no element of (U) remains outside (A). Hence the complement is \(\varnothing\).
Exam Tip
जब (A=U) होता है, तब (U) में (A) से बाहर कोई तत्व नहीं बचता। इसलिए पूरक \(\varnothing\) होता है।
