यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,3,5,7,9\}\) और \(B=A^c\) है, तो \(A\cup B\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,3,5,7,9\}\), 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 direct 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 direct property of complement.
Exam Tip
यदि \(B=A^c\), तो \(A\cup B=A\cup A^c=U\) होगा। यह पूरक का सीधा गुण है।
