यदि \(U={1,2,\ldots,18}\), \(A=\{2,3,5,7,11,13,17\}\) और \(B=\{1,4,9,16\}\), तो (\(A \cup B\)') क्या है?
If \(U={1,2,\ldots,18}\), \(A=\{2,3,5,7,11,13,17\}\), and \(B=\{1,4,9,16\}\), what is (\(A \cup B\)')?
Explanation opens after your attempt
A. ({6,8,10,12,14,15,18})
Concept
First form \(A \cup B\), then remove it from (U). The remaining elements are ({6,8,10,12,14,15,18}).
Why this answer is correct
The correct answer is A. ({6,8,10,12,14,15,18}). First form \(A \cup B\), then remove it from (U). The remaining elements are ({6,8,10,12,14,15,18}).
Exam Tip
पहले \(A \cup B\) बनाएं और फिर उसे (U) से हटाएं। शेष ({6,8,10,12,14,15,18}) हैं।
