यदि \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,2,3,4\}\) और \(B=\{3,4,5\}\) है, तो (\(A\cap B\)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,2,3,4\}\), and \(B=\{3,4,5\}\), what is (\(A\cap B\)^c)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,5,6,7})
Concept
\(A\cap B={3,4}\). Removing (3,4) from (U) gives ({1,2,5,6,7}).
Why this answer is correct
The correct answer is A. ({1,2,5,6,7}). \(A\cap B={3,4}\). Removing (3,4) from (U) gives ({1,2,5,6,7}).
Exam Tip
\(A\cap B={3,4}\) है। (U) से (3,4) हटाने पर ({1,2,5,6,7}) मिलता है।
