यदि (n\(A^c\)=48) और (n(U)=95) है, तो (n(A)) कितना होगा?
If (n\(A^c\)=48) and (n(U)=95), what is (n(A))?
Explanation opens after your attempt
A. (47)
Concept
(A) and \(A^c\) together form (U), so (n(A)=95-48=47). In complement questions, always check the universal set.
Why this answer is correct
The correct answer is A. (47). (A) and \(A^c\) together form (U), so (n(A)=95-48=47). In complement questions, always check the universal set.
Exam Tip
(A) और \(A^c\) मिलकर (U) बनाते हैं, इसलिए (n(A)=95-48=47)। पूरक के प्रश्न में सार्वत्रिक समुच्चय जरूर देखें।
