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
Correct Answer

A. \(\varnothing\)

Step 1

Concept

Here \(A\cup B=U\). Therefore (\(A\cup B\)^c=U^c=\varnothing).

Step 2

Why this answer is correct

The correct answer is A. \(\varnothing\). Here \(A\cup B=U\). Therefore (\(A\cup B\)^c=U^c=\varnothing).

Step 3

Exam Tip

यहां \(A\cup B=U\) है। इसलिए (\(A\cup B\)^c=U^c=\varnothing) होगा।
