Understanding Sets and Venn Diagrams

What is the term for a set that contains no elements?

• Universal set

• Complement set

• Subset

• Null set

Which symbol is used to denote that an element belongs to a set?

• ∪

• ∩

• ∈

• ⊆

If set B is a subset of set A, what can be said about the elements of B?

• B is the universal set

• B and A have no common elements

• B has more elements than A

• All elements of B are in A

What does the union of two sets represent?

• Elements in the universal set

• Elements not in either set

• Elements in either set or both

• Elements common to both sets

In a Venn diagram, what does the intersection of two sets represent?

• Elements in either set

• Elements in both sets

• Elements in the universal set

• Elements in neither set

What does the complement of a set represent?

• Elements in the universal set

• Elements not in the set

• Elements in both sets

• Elements in the set

If A is a set of numbers 1, 2, 4, what is the complement of A in a universal set of numbers 1 to 9?

• 3, 5, 6, 7, 8, 9

• 1, 2, 4

• 5, 6, 7, 8, 9

• 1, 3, 5, 7, 9

In a Venn diagram, what does the shaded region of A complement intersect B represent?

• Elements in neither A nor B

• Elements in B but not in A

• Elements in A but not in B

• Elements in both A and B

How can you exclude a part of a set in a Venn diagram?

• By using a union

• By using an intersection

• By using a complement

• By using a subset

What is the maximum number of sets typically manageable in a Venn diagram?

• Two

• Three

• Four

• Five
