यदि \(U=\{p,q,r,s,t\}\), \(A=\{p,q,r\}\) और \(B=\{r,s\}\) हैं, तो (\(A\cap B\)') क्या होगा?
If \(U=\{p,q,r,s,t\}\), \(A=\{p,q,r\}\), and \(B=\{r,s\}\), what is (\(A\cap B\)')?
Explanation opens after your attempt
Correct Answer
B. ({p,q,s,t})
Concept
\(A\cap B={r}\). Removing (r) from (U) gives ({p,q,s,t}).
Why this answer is correct
The correct answer is B. ({p,q,s,t}). \(A\cap B={r}\). Removing (r) from (U) gives ({p,q,s,t}).
Exam Tip
\(A\cap B={r}\) है। (U) से (r) हटाने पर ({p,q,s,t}) मिलता है।
