2 Probability Spaces This slide show will demonstrate how to draw a probability space and use it to calculate probabilities. The example will draw a probability space for a 6 sided and a 12 sided dice.

3 First we need a table Probability Space

4 Now consider the 6 sided dice Probability Space 6 Sided Dice

5 There are 6 possible outcomes Probability Space 6 Sided Dice

6 Now consider the 12 sided dice Probability Space 12 Sided Dice 6 Sided Dice

7 There are 12 possible outcomes Probability Space 12 Sided Dice 6 Sided Dice

8 Add the scores per combination Probability Space 12 Sided Dice 6 Sided Dice

9 1 + 1 = 2 Probability Space 12 Sided Dice 6 Sided Dice

10 1 + 2 = 3 Probability Space 12 Sided Dice 6 Sided Dice

11 1 + 3 = 4 Probability Space 12 Sided Dice 6 Sided Dice

12 And so on … Probability Space 12 Sided Dice 6 Sided Dice

13 … until the table is filled. Probability Space 12 Sided Dice 6 Sided Dice

14 What use is this? Probability Space 12 Sided Dice 6 Sided Dice

15 There are 72 possible outcomes shown in this table. Only one of them results in a total of 2. What is the probability of rolling the two dice and getting a total score of 2? Probability Space 12 Sided Dice 6 Sided Dice Consider the question below.

16 So the probability is… What is the probability of rolling the two dice and getting a total score of 2? Probability Space 12 Sided Dice 6 Sided Dice

17 Now consider this question. 72 outcomes 6 of them result in a total of 8 What is the probability of rolling the two dice and getting a total score of 8? Probability Space 12 Sided Dice 6 Sided Dice
