11.1 Sets &Venn Diagrams

2. Consider the sample space, the collection of all outcomes, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10. How many elements are in S?
From this set, we can make subsets.
A = even numbers
B= numbers less than 5
What are the elements
in each subset?

3. What elements are in both subsets?
This is called the intersection of A and B
it is written as
Which elements are in A or B but not both?
This is called the union of A and B.
it is written as A U B
Which elements are NOT in A?
This is called the complement of A.
it is written as ~A
