यदि \(U=\{1,2,3,4,5,6,7\}\) और \(A=\{1,3,5,7\}\), तो (\mathcal{P}(A')) में कितने तत्व हैं?
If \(U=\{1,2,3,4,5,6,7\}\) and \(A=\{1,3,5,7\}\), how many elements are in (\mathcal{P}(A'))?
Explanation opens after your attempt
Correct Answer
B. (8)
Concept
(A'={2,4,6}), which has (3) elements. Hence (|\mathcal{P}(A')|=23=8).
Why this answer is correct
The correct answer is B. (8). (A'={2,4,6}), which has (3) elements. Hence (|\mathcal{P}(A')|=23=8).
Exam Tip
(A'={2,4,6}) है, जिसमें (3) तत्व हैं। इसलिए (|\mathcal{P}(A')|=23=8)।
