यदि \(A\subseteq U\), (n(U)=7), और (n(P(A))=16), तो (n(P(A'))) क्या है?
If \(A\subseteq U\), (n(U)=7), and (n(P(A))=16), then what is (n(P(A')))?
Explanation opens after your attempt
B. (8)
Concept
(n(P(A))=16=24), so (n(A)=4). Then (n(A')=7-4=3), and (n(P(A'))=8).
Why this answer is correct
The correct answer is B. (8). (n(P(A))=16=24), so (n(A)=4). Then (n(A')=7-4=3), and (n(P(A'))=8).
Exam Tip
(n(P(A))=16=24), इसलिए (n(A)=4)। तब (n(A')=7-4=3) और (n(P(A'))=8)।
