1. Chapter 1, Unit C
Sets and Venn Diagrams

2. Essential Question
How do we organize relationships between categories?

3. Definitions Set: collection of objects, living, or nonliving.
Example: Set of math teachers at PCHS
Members: specific objects within the set
Example: Shinjo, Kaji, Miwa, RC, Kono, Murata, Yee, Takai, Adaniya, Sumstine, Nakamoto, Nguyen
Set Notation: { } that lists the members separated by commas
{Shinjo, Kaji, Miwa, RC, Kono, Murata, Yee, Takai, Adaniya, Sumstine, Nakamoto, Nguyen}
Ellipses: “…” list continues as expected
Ex: {Shinjo, Kaji, Miwa…Nakamoto, Nguyen}

4. Venn Diagram: SUBSET A is a subset of B (All A are B)
All members of A are also members of B
Example 1: All dogs are animals
Example 2: All bananas are fruit

5. Venn Diagram: DISJOINT
A is disjoint from B (No A are B)
A has no members in common with B
Example 1: Set of boys and girls
Example 2: Set of fruits and vegetables

6. Venn Diagram: OVERLAPPING
A and B are overlapping (Some A are B)
A and B share some of the same members
Example 1: band students and athletes
Example 2: Seniors and Algebra 2

7. Venn Diagram: Overlapping
A and B are overlapping (Some A are not B)
A and B share some members
Example 1: Some teachers are not men
Example 2: Some dogs are not housedogs

8. Venn Diagrams: PRACTICE
Practice #1: All whales are mammals
Practice #2: No fish are mammals
Practice #3: Some women are doctors
Practice #4: Some teachers are not men
Practice #5: Women, Dentist, and Teachers
Practice #6: All politicians are married
Practice #7: If you’re from Hawaii, then you are tan
