यदि \(U=\mathbb{R}\) और (A=(-\infty,2] \cup \(5,\infty\)) है, तो (A') क्या है?
If \(U=\mathbb{R}\) and (A=(-\infty,2] \cup \(5,\infty\)), what is (A')?
Explanation opens after your attempt
Correct Answer
A. (A'=(2,5])
Concept
The point (2) is in (A), while (5) is not in (A). Therefore the complement is (A'=(2,5]).
Why this answer is correct
The correct answer is A. (A'=(2,5]). The point (2) is in (A), while (5) is not in (A). Therefore the complement is (A'=(2,5]).
Exam Tip
(2) समुच्चय (A) में है और (5) समुच्चय (A) में नहीं है। इसलिए पूरक (A'=(2,5]) है।
