Week 6 - Venn Diagrams Vocabulary

Vocabulary flashcards covering core Venn diagram concepts from Week 6 notes.

Venn diagram

A diagram using overlapping circles to represent relationships among sets, showing unions, intersections, and complements.

Set

A collection of distinct objects treated as a single group.

Universe (U)

The total set of all elements being considered in a given context.

Union (A ∪ B)

The set of elements that are in A or in B (or in both); represents 'at least one' of the sets.

Intersection (A ∩ B)

The set of elements that are common to both A and B.

Complement (A')

The set of elements not in A, within the universe U.

Three-set Venn diagram

A Venn diagram with three sets (A, B, C) showing all possible regions of overlap and exclusivity.

Two-set Venn diagram

A Venn diagram with two sets (A and B) showing shared and exclusive regions.

Only in A

Elements that belong to A but not to B (A ext B).

Only in B

Elements that belong to B but not to A (B ext A).

At least one

Another way to say the union; elements that belong to A, B, or both.

Neither

Elements that are in the universe but not in any of the considered sets.

Shading

Marking or coloring regions of a Venn diagram to represent a specific set relationship (e.g., A ∪ B, A ∩ B, A').

Region

A specific area in a Venn diagram corresponding to a unique combination of membership across sets (e.g., A ∩ B, A ∩ B', etc.).

Cardinality

The number of elements contained in a set.
