The Universal Set = { -4, 3, -2, -1, 0, 1, 2, 3 ,4} and A = {0}.

What is the complement of A?

• A' = {-4, -3, -2, -1, 0, 1, 2, 3}

• A' = {-3, -2, -1, 1, 2, 3}

• A' = {-4, -3, -2, -1, 1, 2, 3, 4}

• A' = (-4, -3, -2, -1, 1, 2, 3, 4)

If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∪ B?

• A ∪ B = {3, 5, 7}

• A ∪ B = {2, 3, 5, 7}

• A ∪ B = {2, 3, 5, 7, 9}

• A ∪ B = {1, 2, 3, 5, 7, 9}

Find the cardinality of set A:

A = {14, 16, 18, 20, 22, 24}

Let A = {2, 3, 4, 5, 6, 7} B = {2, 4, 7, 8) and C = {2, 4}.

Fill in the blanks by ⊂ or ⊄ to make the resulting statements true.

B __ A

• ⊂

• ⊄
