Venn Diagram: Example Using the numbers 0, 1, 2, , 9 illustrate the sets: and Solution: Use a Venn diagram Using the numbers 0, 1, 2, , 9 illustrate the sets: and

4 A B 4 is in BOTH sides Using the numbers 0, 1, 2, , 9 illustrate the sets: and 7

4 9 A B 7 and 9 are only in set A Using the numbers 0, 1, 2, , 9 illustrate the sets: and

1 7 4 9 A 2 3 5

B 1, 2, 3 and 5 are only in set B Using the numbers 0, 1, 2, , 9 illustrate the sets: and 0 1 7
