9-3 Sample Spaces 3 2 6 3 2 6 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. You can make an organized list to show all possible outcomes of an experiment.

9-3 Sample Spaces 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? Additional Example 1: Problem Solving Application

8
9-3 Sample Spaces 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. Additional Example 1 Continued The other bag has a red tile and a blue tile.

9-3 Sample Spaces 2 Make a Plan You can make an organized list to show all possible outcomes. Additional Example 1 Continued

10
9-3 Sample Spaces Solve 3 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. Additional Example 1 Continued BG RG BB RB BR RR Bag 2Bag 1

11
9-3 Sample Spaces Look Back 4 Each possible outcome that is recorded in the list is different. Additional Example 1 Continued

12
9-3 Sample Spaces 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
9-3 Sample Spaces 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? Additional Example 2: Using a Tree Diagram to Find a Sample Space Make a tree diagram to show the sample space.

14
9-3 Sample Spaces Check It Out: Example 2 Shauna spins the spinner at left and flips a coin. Complete the tree diagram. What are all the possible outcomes? How many outcomes are in the sample space?

15
9-3 Sample Spaces Check It Out: Example 2 Continued 1 H T 2 3 4 The possible outcomes are 1H, 1T, 2H, 2T, 3H, 3T, 4H, and 4T. There are eight possible outcomes.

16
9-3 Sample Spaces In Additional Example 1, there are three outcomes for the first bag and two outcomes for the second bag. In Additional Example 2, there are four outcomes for the cards and two outcomes for the tiles. Cards Tiles First bagSecond bag

17
9-3 Sample Spaces 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
9-3 Sample Spaces Carrie rolls two 1–6 number cubes. How many outcomes are possible? Additional Example 3: Application The first number cube has 6 outcomes. The second number cube has 6 outcomes List the number of outcomes for each separate experiment. 6 · 6 = 36 There are 36 possible outcomes when Carrie rolls two 1 – 6 number cubes. Use the Fundamental Counting Principle.

19
9-3 Sample Spaces 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
9-3 Sample Spaces 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.
