यदि (U=[-2,3]) और (A=(-1,2]) है, तो \(A^c\) क्या होगा?

If (U=[-2,3]) and (A=(-1,2]), what is \(A^c\)?

Explanation opens after your attempt
Correct Answer

A. ([-2,-1]\cup(2,3])

Step 1

Concept

(-1) is not included in (A), so (-1) is in the complement. (2) is in (A), so the complement starts after (2).

Step 2

Why this answer is correct

The correct answer is A. ([-2,-1]\cup(2,3]). (-1) is not included in (A), so (-1) is in the complement. (2) is in (A), so the complement starts after (2).

Step 3

Exam Tip

(A) में (-1) शामिल नहीं है, इसलिए (-1) पूरक में आएगा। (2) (A) में है, इसलिए पूरक (2) के बाद शुरू होगा।
