यदि \(U=\mathbb{R}\) और (A=(2,5)), तो \(A^{c}\) क्या है?
If \(U=\mathbb{R}\) and (A=(2,5)), what is \(A^{c}\)?
Explanation opens after your attempt
Correct Answer
B. (\(-\infty,2]\cup[5,\infty\))
Concept
((2,5)) does not include endpoints, so the complement includes (2) and (5). Remember bracket changes in interval complements.
Why this answer is correct
The correct answer is B. (\(-\infty,2]\cup[5,\infty\)). ((2,5)) does not include endpoints, so the complement includes (2) and (5). Remember bracket changes in interval complements.
Exam Tip
((2,5)) में अंतिम बिंदु शामिल नहीं हैं, इसलिए पूरक में (2) और (5) शामिल होंगे। अंतराल के पूरक में कोष्ठक बदलना याद रखें।
