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
Correct Answer

A. ({2,3,4,6,8,9,10,12,14,15})

Step 1

Concept

(A) and (A') together form (U) and are disjoint. So subtract (A') from (U).

Step 2

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).

Step 3

Exam Tip

(A) और (A') मिलकर (U) बनाते हैं और अलग-अलग रहते हैं। इसलिए (U) से (A') हटाएं।
