यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,3,5,7\}\) और \(B=\{1,2,3,4,5\}\) है, तो ((B-A)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,3,5,7\}\), and \(B=\{1,2,3,4,5\}\), what is ((B-A)^c)?
Explanation opens after your attempt
Correct Answer
A. ({2,3,5,6,7,8,9})
Concept
First (B-A={1,4}). Removing it from (U) gives ((B-A)^c={2,3,5,6,7,8,9}).
Why this answer is correct
The correct answer is A. ({2,3,5,6,7,8,9}). First (B-A={1,4}). Removing it from (U) gives ((B-A)^c={2,3,5,6,7,8,9}).
Exam Tip
पहले (B-A={1,4}) है। (U) से इसे हटाने पर ((B-A)^c={2,3,5,6,7,8,9}) मिलता है।
