यदि \(U=\{a,b,c,d,e,f\}\), \(A=\{a,b,d\}\), और \(B=\{b,c,d\}\), तो (\(A\cup B\)') क्या है?
If \(U=\{a,b,c,d,e,f\}\), \(A=\{a,b,d\}\), and \(B=\{b,c,d\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
Correct Answer
A. ({e,f})
Concept
\(A\cup B={a,b,c,d}\), so (\(A\cup B\)'={e,f}). First find the union and then take the complement.
Why this answer is correct
The correct answer is A. ({e,f}). \(A\cup B={a,b,c,d}\), so (\(A\cup B\)'={e,f}). First find the union and then take the complement.
Exam Tip
\(A\cup B={a,b,c,d}\), इसलिए (\(A\cup B\)'={e,f})। पहले संघ निकालें फिर पूरक लें।
