1. **Problem:** Draw and explain sets like $A$ or $B$ with an example, not in general scope. 2. **Example sets:** Let $A=\{1,2,3\}$ and $B=\{3,4,5\}$. 3. **What each set means:** A set is just a collection of items. 4. **How to draw them:** We can show each set as a circle with the elements written inside. 5. **Example drawing idea:** - Put $1,2,3$ inside circle $A$. - Put $3,4,5$ inside circle $B$. - The number $3$ belongs to both sets, so it goes in the overlap. 6. **Important rule:** If an element is in both sets, it belongs in the overlapping region. 7. **Final example answer:** - $A=\{1,2,3\}$ - $B=\{3,4,5\}$ - Common element: $3$ - Only in $A$: $1,2$ - Only in $B$: $4,5$
