यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3\}\) और \(B=\{4,5\}\) है, तो \(A^c\cap B^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3\}\), and \(B=\{4,5\}\), what is \(A^c\cap B^c\)?
Explanation opens after your attempt
A. ({6,7,8})
Concept
(A^c\cap B^c=\(A\cup B\)^c). Since \(A\cup B={1,2,3,4,5}\), the remaining elements are (6,7,8).
Why this answer is correct
The correct answer is A. ({6,7,8}). (A^c\cap B^c=\(A\cup B\)^c). Since \(A\cup B={1,2,3,4,5}\), the remaining elements are (6,7,8).
Exam Tip
(A^c\cap B^c=\(A\cup B\)^c) है। \(A\cup B={1,2,3,4,5}\), इसलिए बचे तत्व (6,7,8) हैं।
