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
Correct Answer

B. (8)

Step 1

Concept

(n(P(A))=16=24), so (n(A)=4). Then (n(A')=7-4=3), and (n(P(A'))=8).

Step 2

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).

Step 3

Exam Tip

(n(P(A))=16=24), इसलिए (n(A)=4)। तब (n(A')=7-4=3) और (n(P(A'))=8)।
