यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4,5\}\) और \(B=\{4,5,6,7\}\) है, तो \(A^c\cup B^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4,5\}\), and \(B=\{4,5,6,7\}\), what is \(A^c\cup B^c\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,3,6,7,8,9,10})
Concept
(A^c\cup B^c=\(A\cap B\)^c). Since \(A\cap B={4,5}\), remove it from (U) to get the answer.
Why this answer is correct
The correct answer is A. ({1,2,3,6,7,8,9,10}). (A^c\cup B^c=\(A\cap B\)^c). Since \(A\cap B={4,5}\), remove it from (U) to get the answer.
Exam Tip
(A^c\cup B^c=\(A\cap B\)^c) होता है। \(A\cap B={4,5}\), इसलिए (U) से इसे हटाने पर उत्तर मिलता है।
