यदि (n(P(A'))=64) और (n(U)=10), तो (n(A)) क्या है?
If (n(P(A'))=64) and (n(U)=10), then what is (n(A))?
Explanation opens after your attempt
A. (4)
Concept
\(64=2^6\), so (n(A')=6). Since (n(U)=10), (n(A)=10-6=4).
Why this answer is correct
The correct answer is A. (4). \(64=2^6\), so (n(A')=6). Since (n(U)=10), (n(A)=10-6=4).
Exam Tip
\(64=2^6\), इसलिए (n(A')=6)। चूंकि (n(U)=10), इसलिए (n(A)=10-6=4)।
