यदि \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\) और \(B=\{3,4\}\) हैं, तो (\(A\cup B\)) क्या है?
If \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\), and \(B=\{3,4\}\), what is (\(A\cup B\))?
Explanation opens after your attempt
A. ( {1,2,3,4} )
Concept
\(A\cup B\) contains all distinct elements of (A) and (B). (U) only gives the universal set here.
Why this answer is correct
The correct answer is A. ( {1,2,3,4} ). \(A\cup B\) contains all distinct elements of (A) and (B). (U) only gives the universal set here.
Exam Tip
\(A\cup B\) में (A) और (B) के सभी अलग-अलग अवयव आते हैं। (U) यहां केवल सार्वत्रिक समुच्चय की जानकारी देता है।
