यदि \(U=\{a,b,c,d,e\}\), \(A=\{a,c,e\}\) और \(B=\{b,e\}\), तो (\(A\cup B\)') क्या है?
If \(U=\{a,b,c,d,e\}\), \(A=\{a,c,e\}\), and \(B=\{b,e\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
A. ({d})
Concept
\(A\cup B={a,b,c,e}\), so the only remaining element in (U) is (d). Find the union before taking complement.
Why this answer is correct
The correct answer is A. ({d}). \(A\cup B={a,b,c,e}\), so the only remaining element in (U) is (d). Find the union before taking complement.
Exam Tip
\(A\cup B={a,b,c,e}\), इसलिए (U) में बचा तत्व (d) है। पूरक निकालने से पहले संघ पूरा करें।
