If \(U=\mathbb{R}\) and (A=[-2,4)), what is (A')?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,-2\) \cup [4,\infty))
Concept
(-2) is in (A), so it is not in the complement, while (4) is not in (A), so it is in the complement.
Why this answer is correct
The correct answer is A. (\(-\infty,-2\) \cup [4,\infty)). (-2) is in (A), so it is not in the complement, while (4) is not in (A), so it is in the complement.
Exam Tip
(-2) समुच्चय (A) में है इसलिए पूरक में नहीं आएगा, पर (4) (A) में नहीं है इसलिए पूरक में आएगा।
