यदि \(U=\{7,8,9\}\) और \(A=\varnothing\) है, तो \(A^c\) क्या होगा?
If \(U=\{7,8,9\}\) and \(A=\varnothing\), what will \(A^c\) be?
Explanation opens after your attempt
Correct Answer
A. (U)universal set
Concept
No element is removed from \(\varnothing\), so the whole (U) comes in the complement. Remember that \(\varnothing^c=U\).
Why this answer is correct
The correct answer is A. (U) / universal set. No element is removed from \(\varnothing\), so the whole (U) comes in the complement. Remember that \(\varnothing^c=U\).
Exam Tip
\(\varnothing\) से कोई तत्व नहीं हटता, इसलिए पूरा (U) पूरक में आता है। याद रखें कि \(\varnothing^c=U\) होता है।
