Sets and Venn diagrams (Independent Prac)

Front

What is a set?

Back

A set is a collection of distinct objects, considered as an object in its own right. For example, A = {1, 2, 3} is a set.

Front

What does A ∩ B represent?

Back

A ∩ B represents the intersection of sets A and B, which includes all elements that are common to both sets.

Front

What does A ∪ B represent?

Back

A ∪ B represents the union of sets A and B, which includes all elements that are in either set A, set B, or both.

Front

What is the complement of a set A?

Back

The complement of a set A, denoted A', includes all elements not in A.

Front

If A = {1, 2, 3} and B = {2, 3, 4}, what is A ∩ B?

Back

A ∩ B = {2, 3}

Front

If A = {1, 2, 3} and B = {2, 3, 4}, what is A ∪ B?

Back

A ∪ B = {1, 2, 3, 4}

Front

How do you represent the complement of set A in a Venn diagram?

Back

The complement of set A is represented by shading the area outside of circle A in the Venn diagram.

Front

What is the formula for the number of elements in the union of two sets?

Back

The formula is |A ∪ B| = |A| + |B| - |A ∩ B|.

Front

How many elements are in the set A = {1, 2, 3, 4, 5}?

Back

There are 5 elements in set A.

Front

What does it mean if two sets are disjoint?

Back

Two sets are disjoint if they have no elements in common, meaning A ∩ B = ∅.
