यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\) और \(B=\{2,3,5,8\}\) है, तो ((A-B)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\), and \(B=\{2,3,5,8\}\), what is ((A-B)^c)?
Explanation opens after your attempt
Correct Answer
A. ({2,3,4,5,6,8})
Concept
First (A-B={1,7}). Removing it from (U) gives ((A-B)^c={2,3,4,5,6,8}).
Why this answer is correct
The correct answer is A. ({2,3,4,5,6,8}). First (A-B={1,7}). Removing it from (U) gives ((A-B)^c={2,3,4,5,6,8}).
Exam Tip
पहले (A-B={1,7}) है। (U) से इसे हटाने पर ((A-B)^c={2,3,4,5,6,8}) मिलता है।
