Basic Set Operations

Front

What is the union of two sets A and B?

Back

The union of two sets A and B, denoted as A ∪ B, is the set of elements that are in A, in B, or in both.

Front

What is the intersection of two sets A and B?

Back

The intersection of two sets A and B, denoted as A ∩ B, is the set of elements that are common to both A and B.

Front

What does A - B represent?

Back

A - B represents the set of elements that are in A but not in B.

Front

What is the complement of a set A?

Back

The complement of a set A, denoted as A', is the set of all elements in the universal set U that are not in A.

Front

If U = {1, 2, 3, 4, 5, 6} and A = {1, 2, 3, 4}, what is A'?

Back

A' = {5, 6}

Front

If A = {1, 2, 3} and B = {3, 4, 5}, what is A ∩ B?

Back

A ∩ B = {3}

Front

If A = {1, 2, 3} and B = {4, 5, 6}, what is A ∪ B?

Back

A ∪ B = {1, 2, 3, 4, 5, 6}

Front

What is the difference B - A if A = {1, 2} and B = {1, 2, 3, 4}?

Back

B - A = {3, 4}

Front

What is the universal set?

Back

The universal set is the set that contains all possible elements for a particular discussion or problem.

Front

What does it mean for two sets to be disjoint?

Back

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