यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,7\}\) और \(B=\{2,4,6\}\) है, तो \(A\cup B\) क्या है?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,7\}\), and \(B=\{2,4,6\}\), what is \(A\cup B\)?
Explanation opens after your attempt
A. ( {1,2,4,6,7} )
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. ( {1,2,4,6,7} ). \(A\cup B\) 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 हैं। (U) केवल सार्वत्रिक समुच्चय है, उत्तर हमेशा पूरा (U) नहीं होता।
