© 2006 Baylor University Slide 3 Set Definitions & Notation  A Set is a group of things that share a common rule. Decimal Number set Binary Number set

© 2006 Baylor University Slide 4 Rules for Sets  A Set can be Finite  A Set can have an Infinite number of Elements  “Universal” Set Concept No Zero

© 2006 Baylor University Slide 5 General Set Notation a Finite Set an Infinite Set a “Closed Infinite Interval”

© 2006 Baylor University Slide 6 More Rules for Sets an Infinite Set

© 2006 Baylor University Slide 7 Set Mathematics  Sets are Equal - if all Elements are the same Subset: A is “Contained” in B - A is a “Proper” Subset  the “Null” Set also called the “Empty” set

© 2006 Baylor University Slide 8 UNION of Sets All of A, OR All of B, OR Both “OR” A OR B

© 2006 Baylor University Slide 9 INTERSECTION of Sets A “intersect” B Only Elements in A AND B both at the same time “AND”

© 2006 Baylor University Slide 10 INTERSECTION of Sets Sets C and B are “Disjoint”

© 2006 Baylor University Slide 11 COMPLEMENT of Sets “NOT” is also a Boolean Operator
