यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,3,5,7\}\) और \(C=\{3,5,8\}\) हैं, तो (A\cap \(B\setminus C\)) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,3,5,7\}\), and \(C=\{3,5,8\}\), what is (A\cap \(B\setminus C\))?
Explanation opens after your attempt
Correct Answer
A. ( {2} )
Concept
\(B\setminus C={2,7}\), then intersecting with (A) leaves (2). Do the difference first, then the intersection.
Why this answer is correct
The correct answer is A. ( {2} ). \(B\setminus C={2,7}\), then intersecting with (A) leaves (2). Do the difference first, then the intersection.
Exam Tip
\(B\setminus C={2,7}\), फिर (A) से प्रतिच्छेद लेने पर (2) बचता है। पहले अंतर और फिर प्रतिच्छेद करें।
