Unit 10 – Logic and Venn Diagrams Venn Diagram: Example
Solution: Use a Venn diagram 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 7 2 4 3 9 5 A B 1, 2, 3 and 5 are only in set B
Using the numbers 0, 1, 2, … , 9 illustrate the sets: and 1 7 2 4 6 3 9 8 5 A B 0, 6 and 8 are not in A or B
