यदि \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,3,5\}\) और \(B=\{2,3,4\}\) है, तो \(A\cup B\) क्या है?
If \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,3,5\}\), and \(B=\{2,3,4\}\), what is \(A\cup B\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3,4,5} )
Concept
\(A\cup B\) contains all distinct elements of (A) and (B). (U) is only the universal set; the answer is not always the whole (U).
Why this answer is correct
The correct answer is A. ( {1,2,3,4,5} ). \(A\cup B\) contains all distinct elements of (A) and (B). (U) is only the universal set; the answer is not always the whole (U).
Exam Tip
\(A\cup B\) में (A) और (B) के सभी अलग-अलग अवयव आते हैं। (U) केवल संदर्भ समुच्चय है, हर बार पूरा (U) उत्तर नहीं होता।
