यदि \(U={1,2,\ldots,18}\), \(A=\{2,4,6,8,10,12,14,16,18\}\) और \(B=\{3,6,9,12,15,18\}\), तो \(A'\cup B'\) क्या है?

If \(U={1,2,\ldots,18}\), \(A=\{2,4,6,8,10,12,14,16,18\}\), and \(B=\{3,6,9,12,15,18\}\), what is \(A'\cup B'\)?

Explanation opens after your attempt
Correct Answer

A. ({1,2,3,4,5,7,8,9,10,11,13,14,15,16,17})

Step 1

Concept

(A'\cup B'=\(A\cap B\)'). Since \(A\cap B={6,12,18}\), remove these from (U).

Step 2

Why this answer is correct

The correct answer is A. ({1,2,3,4,5,7,8,9,10,11,13,14,15,16,17}). (A'\cup B'=\(A\cap B\)'). Since \(A\cap B={6,12,18}\), remove these from (U).

Step 3

Exam Tip

(A'\cup B'=\(A\cap B\)') है। \(A\cap B={6,12,18}\), इसलिए इन्हें (U) से हटाएं।
