यदि \(U=\mathbb{Z}\) और \(A={x:x \in \mathbb{Z}, x>0}\), तो \(A^{c}\) क्या दर्शाता है?
If \(U=\mathbb{Z}\) and \(A={x:x \in \mathbb{Z}, x>0}\), what does \(A^{c}\) represent?
Explanation opens after your attempt
Correct Answer
B. \({x:x \in \mathbb{Z}, x\le 0}\)
Concept
(A) contains positive integers, so the complement includes (0) and negative integers. Always check the boundary value in inequalities.
Why this answer is correct
The correct answer is B. \({x:x \in \mathbb{Z}, x\le 0}\). (A) contains positive integers, so the complement includes (0) and negative integers. Always check the boundary value in inequalities.
Exam Tip
(A) में धन पूर्णांक हैं, इसलिए पूरक में (0) और ऋण पूर्णांक आते हैं। असमानता में सीमांत मान जरूर जांचें।
