set that has unlimited and uncountable element

only have one element (singleton)

also called null set

totality of elements under consideration denoted by U

number of elements in a set

G={a,e,io,u}, What is the cardinality?

if element of A is also an element of B

A is a _______________________of B, written , if and only if, every element of A is in B but there is at least one element of B that is not in A

 , if and only if, every element of A is in B and every element of B is in A

A ____________ is the set of all subsets of a given set, containing the empty set and the original set. It is denoted by
