1. Determining the Sample Space
There are four ways to determine the sample
space, those are:
1. Listing
2. Tree Diagram
3. Table
4. Cartesian Diagram

2. Listing
We have a coin which have number side and
picture side. The sample space are :
S={N,P}
n(S)=2

3. Tree Diagram
We have a coin which have number side and
picture side. Then, we throw it for two times
We can find the sample space by using tree
diagram like this one.

4. N presents the Number side
P presents the Picture side
S = {(N,N),(N,P),(P,N), (P,P)}

5. Table
P N
P (P,P) (P,N)
N (N,P) (N,N)
The sample space is {(P,P),(P,N),(N,P),(N,N)}
The sample points are (P,P),(P,N),(N,P),(N,N)

6. Cartesian Diagram
The sample points are
(P,P),(P,N),(N,P),(N,N)
The sample space (S) is
{(P,P),(P,N),(N,P),(N,N)}

7. Look at the coin which has number side and picture side.
Picture side(P) Number side(N)
Then :
Sample space (S) = { N , P }
Sample point = N and P, then n(S) = 2
example

8. Then :
Sample space (S) = { 1, 2, 3, 4, 5, 6 }
Sample point = 1, 2, 3, 4, 5, and 6, then n(S) = 6
The Probability : Number1 Number 2 Number 3 Number 4 Number 5 Number6
Question : What does sample space mean?
