(Solved): Let S be the universal set, where: S = {1, 2, 3, ..., 18, 19, 20} Let sets A and B be subsets of S, ...

Let $S$ be the universal set, where: $S=\{1,2,3,\dots ,18,19,20\}$ Let sets $A$ and $B$ be subsets of $S$, where: Set $A=\{3,6,9,10,11,12,15,18\}$ $\text{ Set }B=\{1,3,4,6,7,11,12,13,16,18,19,20\}$ Find the following: LIST the elements in the set $(A?B)$ : $(A?B)=\{$ Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE LIST the elements in the set $(A?B)$ : $(A?B)=\{$ Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE You may want to draw a Venn Diagram to help answer this question.
