Quiz 1 Set, Structure and Function

The total number of subsets of {A, B, C} is _____.

8

Given A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8, 10}, C = {1, 5, 6, 7, 9}

A ∩ B = Empty set

If A ⊂ B, then

A ∪ B = B

D = {x | x is a whole number} E = {x | x is a perfect square < 36} F = {x | x is an even number between 20 and 30}

F ⊂ D (E ∩ F) is the empty set.

If A ⊂ B, B may have more elements than A.

True

Set A = { X | X is an even whole number between 0 and 2} =Set A =

True

This symbol means every element is in both sets. (A ⊆ B)

True

A = {1, 3, 5, 7, 9} B = {2, 4, 6, 8, 10} C = {1, 5, 6, 7, 9} A ∪ B=

integers from 1 to 10 inclusive

A = {1, 3, 5, 7, 9} B = {2, 4, 6, 8, 10} C = {1, 5, 6, 7, 9} A ∩ (B ∩ C) =

{ }

A = {1, 3, 5, 7, 9} B = {2, 4, 6, 8, 10} C = {1, 5, 6, 7, 9} A ∪ (B ∩ C) =

{1, 3, 5, 6, 7, 9}

A = {1, 3, 5, 7, 9} B = {2, 4, 6, 8, 10} C = {1, 5, 6, 7, 9} A ∩ (B ∪ C) =

{1, 5, 7, 9}
