Math 116: Introduction to set and set notation. Set: a collection of objects, things or numbers.  The universal set it the set of all possible elements of a set used in the problem  Denoted by: Examples of sets:  1,2,3,4,5,6,7  Ron, Phil, Kate, Nate  Delaware, Virginia, California, Washington Roster Notation: all elements are listed one by one and separated by comas  {1,5,7,9,11} {Mark, Matt, Millie} Builder Set Notation: {x|x is a description}  Example: {x|x is an amino acid} Roster Notation Builder Set Notation {A,E,I,O,U} {x|x is a vowel} {Atlantic, Pacific, Indian} {x|x is an ocean} {3,6,9,12,14,16,18} {x|x is an odd number} Well Defined Set:  A set is well defined if the elements of the set are clearly defined  If a set is well defined, then there should not be any confusion of what the elements are in the set. Examples:  x|x is a vowel: well defined  x|x is a beautiful person: not well defined Write the following sets in builder set notation:  {Virginia, Vermont}: {x|x is a state that begins with V}  {}: {x|x is a square}  {Iowa, Utah, Ohio}:{x|x is a state with 4 letters} Write the following in roster set notation: {x|x is a state that begins with I}: {Indiana, Iowa, Idaho, Illinois} {x|x is a state that boarders Virginia}: {Maryland, West Virginia, Tennessee, North Carolina, Kentucky} Important Sets:  Natural numbers/ counting numbers: N= {1,2,3,4….}  Whole numbers: W= {0,1,2,3,4,5,6….}  Integers: Z= {-5, -4, -3, -2, -1….} Important symbols: Empty Set: a set that contains no elements, also called the null set{} True of False: B  {A,B,C,D,E}: True A  {{A}, {B},{C},{D}}: False Equivalent Sets: they are equivalent if they have the same number of elements  Example: {1,2,3} and {A, B, C}  Symbol:  Are the following sets equivalent?  {A, B, C}  {E, F, G} Subsets:  A set B is a subset of C. every element in B is an element of C  Symbolically B is a subset of c is written as: B  C Example: Is A a subset of C? Yes, because every element in set A also Lies in set C A= {1,2,3,4,5} C= {1,2,3,4,5,6,7} Proper subset:  A set B is a proper subset if C if every element of B is an element of set C and has at least one element that does not lie in set B Example: Is A a proper subset of C? A  C, yes because every element that lies in set A also lies in set C with an extra element. A= {1,2,3,4,5} C= {1,2,3,4,5,6,7} List all of the possible subsets of {A, B, C} {A} {B} {C} {} {A,B} {B,C} {A,C} Number of elements in Set Subsets 0 0 1=2 1 2=2 1 2 4=2 2 3 3 8=2 4 16=2 4 5 32=2 5 6 6 64=2  Formula to find the number of subsets of a given set A with n elements: n  S=2  S= 26  S=64 Example: how many subsets does a set with 10 elements have?  S= 2n 10  S= 2  S= 1024
