यदि \(U=\{a,b,c,d,e,g,h\}\), \(A=\{a,c,g\}\) और \(B=\{b,c,h\}\), तो (\(A\cup B\)') क्या है?
If \(U=\{a,b,c,d,e,g,h\}\), \(A=\{a,c,g\}\) and \(B=\{b,c,h\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
A. ({d,e})
Concept
\(A\cup B={a,b,c,g,h}\). The elements left outside it in (U) are (d,e).
Why this answer is correct
The correct answer is A. ({d,e}). \(A\cup B={a,b,c,g,h}\). The elements left outside it in (U) are (d,e).
Exam Tip
\(A\cup B={a,b,c,g,h}\) है। (U) में इसके बाहर (d,e) बचते हैं।
