यदि \(U=\{1,2,3\}\) और \(A=\varnothing\) है, तो \(A^c\) क्या होगा?
If \(U=\{1,2,3\}\) and \(A=\varnothing\), what is \(A^c\)?
Explanation opens after your attempt
Correct Answer
A. (U)universal set
Concept
\(\varnothing\) has no element, so all elements of (U) come in the complement. Remember that \(\varnothing^c=U\).
Why this answer is correct
The correct answer is A. (U) / universal set. \(\varnothing\) has no element, so all elements of (U) come in the complement. Remember that \(\varnothing^c=U\).
Exam Tip
\(\varnothing\) में कोई तत्व नहीं होता, इसलिए (U) के सभी तत्व पूरक में आते हैं। याद रखें कि \(\varnothing^c=U\) होता है।
