यदि \(U=\{1,2,3,4,5,6,7\}\), \(A=\{2,4,6\}\), तो \(A^{c}\cap A\) में कितने अवयव हैं?
If \(U=\{1,2,3,4,5,6,7\}\), \(A=\{2,4,6\}\), how many elements are in \(A^{c}\cap A\)?
Explanation opens after your attempt
Correct Answer
A. (0)
Concept
(A) and \(A^{c}\) are disjoint, so their intersection is empty. The cardinality of the empty set is (0).
Why this answer is correct
The correct answer is A. (0). (A) and \(A^{c}\) are disjoint, so their intersection is empty. The cardinality of the empty set is (0).
Exam Tip
(A) और \(A^{c}\) में कोई साझा अवयव नहीं होता, इसलिए प्रतिच्छेद खाली है। रिक्त समुच्चय की अवयव संख्या (0) होती है।
