Sagot :

Roster method (listing method):
1) {January, June, July}
2) {0, 2, 4, 6, 8, 10}
3) {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}  
       *prime numbers are numbers with only two factors, 1 and itself

Builder:
4) notice that all the elements in the set are even numbers between 0 and 22
    {x| x is an even number between 0 and 22}
5) {x| x is a letter in the word "monkey"}
6) {x| x is a letter in the word "philippines"}

Note:
{ } is important because it indicates that it is a set
| means such that. Others use :
No elements in a set should be the same (this explains #6)
