यदि \(A=\{1,2\}\) और \(U=\{1,2,3\}\) है तो (\mathcal{P}(A')) क्या होगा?
If \(A=\{1,2\}\) and \(U=\{1,2,3\}\), what is (\mathcal{P}(A'))?
Explanation opens after your attempt
Correct Answer
A. {\(\emptyset,{3}\)}
Concept
First (A'={3}). Then (\mathcal{P}(A')={\emptyset,{3}}).
Why this answer is correct
The correct answer is A. {\(\emptyset,{3}\)}. First (A'={3}). Then (\mathcal{P}(A')={\emptyset,{3}}).
Exam Tip
पहले (A'={3}) मिलेगा। फिर (\mathcal{P}(A')={\emptyset,{3}}) होगा।
