यदि (n(U)=30) और (n\(A^c\)=18) है, तो (n(A)) कितना होगा?
If (n(U)=30) and (n\(A^c\)=18), what is (n(A))?
Explanation opens after your attempt
A. (12)
Concept
(n(A)=n(U)-n\(A^c\)). Therefore (30-18=12) is correct.
Why this answer is correct
The correct answer is A. (12). (n(A)=n(U)-n\(A^c\)). Therefore (30-18=12) is correct.
Exam Tip
(n(A)=n(U)-n\(A^c\)) होता है। इसलिए (30-18=12) सही है।
