यदि \(U=\{1,2,3,4,5,6,7,8,9\}\) और \(A=\{2,3,5,7\}\) है, तो \(A^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9\}\) and \(A=\{2,3,5,7\}\), what is \(A^c\)?
Explanation opens after your attempt
A. ({1,4,6,8,9})
Concept
(A) contains the given prime numbers, so the remaining elements are in \(A^c\). Do not treat (1) as a prime number.
Why this answer is correct
The correct answer is A. ({1,4,6,8,9}). (A) contains the given prime numbers, so the remaining elements are in \(A^c\). Do not treat (1) as a prime number.
Exam Tip
(A) में दी हुई अभाज्य संख्याएं हैं, इसलिए बाकी तत्व \(A^c\) में हैं। (1) को अभाज्य न मानें।
