एक वेन आरेख में (n\(A\triangle B\)=82) और (n\(A\cup B\)=119) है। (n\(A\cap B\)) कितना होगा?
In a Venn diagram (n\(A\triangle B\)=82) and (n\(A\cup B\)=119). What is (n\(A\cap B\))?
Explanation opens after your attempt
Correct Answer
A. (37)
Concept
\(A\cup B\) contains both \(A\triangle B\) and \(A\cap B\), so (119-82=37). The symmetric difference does not include the common part.
Why this answer is correct
The correct answer is A. (37). \(A\cup B\) contains both \(A\triangle B\) and \(A\cap B\), so (119-82=37). The symmetric difference does not include the common part.
Exam Tip
\(A\cup B\) में \(A\triangle B\) और \(A\cap B\) दोनों शामिल हैं, इसलिए (119-82=37)। सममित अंतर में साझा भाग नहीं आता।
