**Drawing Venn Diagrams With Sets**

Consider the following information:

- $A$ = {1, 2, 3}
- $B$ = {3, 4, 5}
- Universal Set $U$ = {1, 2, 3, 4, 5, 6, 7}

Draw a Venn Diagram describing the 3 sets.

Consider the following information:

- $A$ = {1, 2, 3}
- $B$ = {4, 5, 6}
- Universal Set $U$ = {1, 2, 3, 4, 5, 6, 7}

Draw a Venn Diagram describing the 3 sets.

**Understanding How to Use Set Notation**

Consider the following information:- Universal set $U$ = {0, 1, 2, 3, 4, 5,...}
- Set $N$ = {all natural numbers}
- Set $A$ = {0}
- Set $B$ = { }

- Consider the following Venn Diagram:
- Universal set $U = \{\mathrm{archery, eating, chess, darts,soccer, basketball, football, volleyball, tennis, badminton}\}$
- Set $A = \{\mathrm{archery, eating, chess, darts}\}$
- Set $B = \{\mathrm{soccer, basketball, football, volleyball}\}$

- Consider the following Venn Diagram:
**Drawing and Interpreting Venn Diagrams**Consider the following information:

- Universal Set $U =$ $\mathrm\{-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10\}$
- Set $A$ = {positive odd number up to 10}
- Set $B$ = {positive even number up to 10}
- Set $C$ = {0}
