6. You can make an organized list to show all possible
Because you can roll the numbers 1, 2, 3, 4, 5, and 6 on a number cube, there are 6 possible outcomes. Together, all the possible outcomes of an experiment make up the sample space. 3 2 6 3 2 6
You can make an organized list to show all possible
outcomes of an experiment.

7. Additional Example 1: Problem Solving Application
One bag has a red tile, a blue tile, and a green tile. A second bag has a red tile and a blue tile. Vincent draws one tile from each bag. What are all the possible outcomes? How many outcomes are in the sample space?

8. Understand the Problem
Additional Example 1 Continued 1
Understand the Problem
Rewrite the question as a statement.
• Find all the possible outcomes of drawing one tile from each bag, and determine the size of the sample space.
List the important information:
• There are two bags.
• One bag has a red tile, a blue tile, and a
green tile.
• The other bag has a red tile and a blue tile.

9. Additional Example 1 Continued2
Make a Plan
You can make an organized list to show all
possible outcomes.

10. Additional Example 1 Continued
Solve 3 B G R
Bag 2
Bag 1
Let R = red tile, B = blue tile, and G = green tile.
Record each possible outcome.
The possible outcomes are RR, RB, BR, BB, GR, and GB. There are six possible outcomes in the sample space.

11. Additional Example 1 Continued4
Look Back
Each possible outcome that is recorded in
the list is different.

12. Check It Out: Example 1
Darren has two bags of marbles. One has a green marble and a red marble. The second bag has a blue and a red marble. Darren draws
one marble from each bag. What are all the possible outcomes? How many outcomes are in the sample space?
The four possible outcomes are GB, GR, RB, and RR. There are four possible outcomes in the sample space.

13. Additional Example 2: Using a Tree Diagram to Find a Sample Space
There are 4 cards and 2 tiles in a board game. The cards are labeled N, S, E, and W. The tiles are numbered 1 and 2. A player randomly selects one card and one tile. What are all the possible outcomes? How many outcomes are in the sample space?
Make a tree diagram to show the sample space.

In Additional Example 2, there are four outcomes for the cards and two outcomes for the tiles.

17. The Fundamental Counting Principle states that you can find the total number of outcomes for two or more experiments by multiplying the number of outcomes for each separate experiment.

18. Additional Example 3: Application
Carrie rolls two 1–6 number cubes. How many outcomes are possible?
List the number of outcomes for each separate experiment.
The first number cube has 6 outcomes.
The second number cube has 6 outcomes
6 · 6 = 36
Use the Fundamental Counting Principle.
There are 36 possible outcomes when Carrie rolls
two 1–6 number cubes.

19. Check It Out: Example 3A
Juan tosses a coin and rolls a number cube. How many outcomes are possible?
There are two possible outcomes for the coin. There are six possible outcomes for the number cube.
2 × 6 = 12
There are twelve possible outcomes.

20. Check It Out: Example 3B
Juan rolls a number cube and spins the spinner shown in Check It Out question 2. How many outcomes are possible?
There are six possible outcomes for the number cube. There are four possible outcomes for the spinner.
6 × 4 = 24
There are 24 possible outcomes.
