यदि \(U={1,2,\ldots,15}\) और (A'={1,5,7,11,13}), तो (A) क्या है?
If \(U={1,2,\ldots,15}\) and (A'={1,5,7,11,13}), what is (A)?
Explanation opens after your attempt
A. ({2,3,4,6,8,9,10,12,14,15})
Concept
(A) and (A') together form (U) and are disjoint. So subtract (A') from (U).
Why this answer is correct
The correct answer is A. ({2,3,4,6,8,9,10,12,14,15}). (A) and (A') together form (U) and are disjoint. So subtract (A') from (U).
Exam Tip
(A) और (A') मिलकर (U) बनाते हैं और अलग-अलग रहते हैं। इसलिए (U) से (A') हटाएं।
