यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,4,6,8\}\), तो कौन सा कथन सही है?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,4,6,8\}\), which statement is correct?
Explanation opens after your attempt
Correct Answer
A. \(9\in A^{c}\)
Concept
(9) is in (U) and not in (A), so \(9\in A^{c}\). In membership questions, check both conditions.
Why this answer is correct
The correct answer is A. \(9\in A^{c}\). (9) is in (U) and not in (A), so \(9\in A^{c}\). In membership questions, check both conditions.
Exam Tip
(9) (U) में है और (A) में नहीं है, इसलिए \(9\in A^{c}\)। सदस्यता प्रश्नों में दोनों शर्तें जांचें।
