\(यदि (U={1,2,\ldots,20}), (A={x:x \in U\) तथा \(x \le 8}) और (B={x:x \in U\) तथा \(x \ge 14}), तो ((A \cup B)') क्या है\)?
\(If (U={1,2,\ldots,20}), (A={x:x \in U\) and \(x \le 8}), and (B={x:x \in U\) and \(x \ge 14}), what is ((A \cup B)')\)?
Explanation opens after your attempt
A. ({9,10,11,12,13})
Simple Explanation
\(A \cup B\) में (1) से (8) और (14) से (20) तक के सदस्य हैं। बीच के (9) से (13) तक पूरक में बचते हैं। / \(A \cup B\) contains elements from (1) to (8) and from (14) to (20). The middle elements from (9) to (13) remain in the complement.
