यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3,4\}\) और \(B=\{5,6,7,8\}\) है, तो (\(A\cup B\)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3,4\}\), and \(B=\{5,6,7,8\}\), what is (\(A\cup B\)^c)?
Explanation opens after your attempt
A. \(\varnothing\)
Concept
Here \(A\cup B=U\). Therefore (\(A\cup B\)^c=U^c=\varnothing).
Why this answer is correct
The correct answer is A. \(\varnothing\). Here \(A\cup B=U\). Therefore (\(A\cup B\)^c=U^c=\varnothing).
Exam Tip
यहां \(A\cup B=U\) है। इसलिए (\(A\cup B\)^c=U^c=\varnothing) होगा।
