यदि \(U=\{a,b,c,d,e\}\), \(A=\{a,c,e\}\) और \(B=\{b,c,d\}\), तो (\(A\cup B\)') क्या है?
If \(U=\{a,b,c,d,e\}\), \(A=\{a,c,e\}\) and \(B=\{b,c,d\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
Correct Answer
A. \(\emptyset\)
Concept
\(A\cup B={a,b,c,d,e}=U\). Therefore its complement is the empty set.
Why this answer is correct
The correct answer is A. \(\emptyset\). \(A\cup B={a,b,c,d,e}=U\). Therefore its complement is the empty set.
Exam Tip
\(A\cup B={a,b,c,d,e}=U\) है। इसलिए इसका पूरक खाली समुच्चय है।
