Let \( S \) be the universal set, where: \( S=\{1,2,3, \ldots, 18,19,20\} \) Let sets \( A \) and \( B \) be subsets of \( S \), where: Set \( A=\{3,4,7,11,16,17,18,20\} \) Set \( B=\{1,2,6,8,12,18,19\} \) Find the following: LIST the elements in the set \( (A \cup B) \) : \( (A \cup B)=\{\square \) Enter the elements as a list, separated by commas. If the result is the empty set, enter DN LIST the elements in the set \( (A \cap B) \) : \( (A \cap B)=\{\square \) Enter the elements as a list, separated by commas. If the result is the empty set, enter DN
