यदि \(U=\{1,2,3,4,5,6,7,8\}\) और \(A=\{2,4,6,8\}\) है, तो (n(\mathcal{P}(A'))) कितना होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\) and \(A=\{2,4,6,8\}\), what is (n(\mathcal{P}(A')))?
Explanation opens after your attempt
Correct Answer
C. (16)
Concept
(A'={1,3,5,7}), so (n(A')=4). Hence (n(\mathcal{P}(A'))=24=16).
Why this answer is correct
The correct answer is C. (16). (A'={1,3,5,7}), so (n(A')=4). Hence (n(\mathcal{P}(A'))=24=16).
Exam Tip
(A'={1,3,5,7}) है, इसलिए (n(A')=4)। अतः (n(\mathcal{P}(A'))=24=16) होगा।
