यदि \(U={1,2,3,\ldots,14}\) और \(A^c={2,3,5,7,11,13}\) है, तो (A) में कितने तत्व होंगे?
If \(U={1,2,3,\ldots,14}\) and \(A^c={2,3,5,7,11,13}\), how many elements are in (A)?
Explanation opens after your attempt
A. (8)
Concept
(U) has (14) elements and \(A^c\) has (6) elements. Therefore (n(A)=14-6=8).
Why this answer is correct
The correct answer is A. (8). (U) has (14) elements and \(A^c\) has (6) elements. Therefore (n(A)=14-6=8).
Exam Tip
(U) में (14) तत्व हैं और \(A^c\) में (6) तत्व हैं। इसलिए (n(A)=14-6=8) होगा।
