यदि \(U=\{1,2,3,4,5,6\}\) और \(A=\{1,3,6\}\) है तो (\mathcal{P}(A')) में कितने तत्व होंगे?
If \(U=\{1,2,3,4,5,6\}\) and \(A=\{1,3,6\}\), how many elements will be in (\mathcal{P}(A'))?
Explanation opens after your attempt
Correct Answer
C. (8)
Concept
First (A'={2,4,5}), which has (3) elements. So (\mathcal{P}(A')) has \(2^3=8\) elements.
Why this answer is correct
The correct answer is C. (8). First (A'={2,4,5}), which has (3) elements. So (\mathcal{P}(A')) has \(2^3=8\) elements.
Exam Tip
पहले (A'={2,4,5}) मिलेगा जिसमें (3) तत्व हैं। इसलिए (\mathcal{P}(A')) में \(2^3=8\) तत्व होंगे।
