यदि \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\) और \(B=\{3,4,5\}\) है, तो (\(A\cup B\)') क्या है?
If \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\), and \(B=\{3,4,5\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
Correct Answer
A. ({6})
Concept
\(A\cup B={1,2,3,4,5}\), so its complement is ({6}). First find the union, then take complement.
Why this answer is correct
The correct answer is A. ({6}). \(A\cup B={1,2,3,4,5}\), so its complement is ({6}). First find the union, then take complement.
Exam Tip
\(A\cup B={1,2,3,4,5}\), इसलिए उसका पूरक ({6}) है। पहले संघ निकालें फिर पूरक लें।
