यदि \(U=\{a,b,c,d\}\), \(A=\{a,b\}\) और \(B=\{b,c\}\) हैं, तो (\(A\cap B\)') क्या होगा?
If \(U=\{a,b,c,d\}\), \(A=\{a,b\}\), and \(B=\{b,c\}\), what is (\(A\cap B\)')?
Explanation opens after your attempt
Correct Answer
B. ({a,c,d})
Concept
\(A\cap B={b}\), so its complement is all elements of (U) except (b). Hence ({a,c,d}) is correct.
Why this answer is correct
The correct answer is B. ({a,c,d}). \(A\cap B={b}\), so its complement is all elements of (U) except (b). Hence ({a,c,d}) is correct.
Exam Tip
\(A\cap B={b}\) है, इसलिए उसका पूरक (U) में (b) को छोड़कर बाकी तत्व हैं। अतः ({a,c,d}) सही है।
