### Group 4 Example 15

Method: Probability Tree
3^3=27 (Total Possible Outcomes)
Number of 9s in Total Possible Outcomes: 7

Probability of score being 9: 7/27

1. There should be some annotations so that we can understand what you are trying to explain with the use of the diagrams.

2. Understandable but Vague.

3. It would be good if you can label the diagram. The diagram is understandable. Good Job :D

4. It would be good if there was some description for probability tree.

5. It would be better if you could add in some explanation so that it is easier to understand.

6. It would be better if there was a description on how to use a probability tree.

7. There is not much explanation on the use of the probability tree therefore, it is slightly ambiguous. It would be good if there was more example questions or situations that help to further the understanding of when to use the probability tree.

8. Can you tell us the pros/cons of using a probability tree?

9. Diagram is vague and should have labels and explanation.

10. There is not a good explanation as it does not have a detailed explanation

11. Needs further explanation. What does this numbers represents?

12. Should give a few examples whereby the use of the probability tree is more advantageous than using other methods to deduce the probability of certain events.

14. There should be an explanation of their workings.
