SUBSET

A subset is a set whose elements are all members of another set. The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".

Multiple Choice

If U = {1, 3, 5, 7, 9, 11, 13}, then which of the following are subsets of U.

Multiple Choice

Null or Empty Set

is the set that does not contain anything. It is symbolized or { }.

Element of a Set

An object or idea in a set is called an element (or member) of the set. Notation: The symbol ∈ is used to denote that an element is a member of a set and ∉ is used to denote that an object is not a member of a set.

SUBSET

A subset is a set whose elements are all members of another set. The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".
