यदि \(U={1,2,3,\ldots,12}\), \(A=\{2,3,5,7,11\}\) और \(B=A^c\) है, तो \(A\cup B\) क्या होगा?
If \(U={1,2,3,\ldots,12}\), \(A=\{2,3,5,7,11\}\), and \(B=A^c\), what is \(A\cup B\)?
Explanation opens after your attempt
Correct Answer
A. (U)
Concept
If \(B=A^c\), then \(A\cup B=A\cup A^c=U\). This is a basic property of complement.
Why this answer is correct
The correct answer is A. (U). If \(B=A^c\), then \(A\cup B=A\cup A^c=U\). This is a basic property of complement.
Exam Tip
यदि \(B=A^c\), तो \(A\cup B=A\cup A^c=U\) होगा। यह पूरक का मूल गुण है।
