2. Enumerate 2 ways in writing a set and give 3 examples for each type.

3. Define and give 3 examples for each:

- A well- defined collection of objects is known as a set. 
      Example: { Jose, Juan, John} { paper, pencil, notebook} { bag, plastic bag, pen}
            Note: { } braces are used to enclose sets
- Roster/ Listing Method and Rule Method
      Example: Roster { Johnny, John, John}, {note, book, notebook}, {money,bag,pen}
                     Rule { first four counting numbers} {first four letters} {alphabetically arrange                              names}
- Cardinality of a set- number of elements in a set
                      Ex.- A= {1,2,3,4} n(A)= 4 
                             B= {1,2,3} n(B)= 3
                             C= {1,2} n(C) = 2
- Equivalent set- if the sets have the same number of elements
                      Ex.-  F= {1,2,3,4,5}
                              G= {6,7,8,9,10}
                                = n(F)= 5 n(G)= 5
-Equal set- they have the same number
                      Ex.- F= { 20,40,80}
                             E= { 80,20,40}
                               = F=E
-Null set- it has no elements Ф(this is the symbol)

-Universal set- a set containing all elements of a problem under consideration
