Use and apply knowledge about probability to a range of relevant contexts
Calculate theoretical probabilities and use tree diagrams to investigate the probability of outcomes in simple multiple-event trials
Use knowledge about chance and probability to estimate and interpret the outcomes of common chance events in both numerical and qualitative terms
To estimate probability outcomes
Describe chance events in qualitative format
Calculate theoretical probability and draw tree diagrams

TASK:
Create your own spinner entering items of your choice. Make at least 4 items.
List the sample space on the spinner.
Do you think that there is an even chance for each number to be selected? Why/why not?
Calculate the probability of one of the items on your spinner.
Draw a tree diagram of the possible outcomes of spinning the wheel for at least 3 trials.
What is the probability of the spinner landing on the same item for 3 trials?
What is the probability of the spinner landing on 3 different items after 3 trials?
What is the probability of the spinner landing on an item, then a different item then the same item again?
Select and list 2 of your items. What is the probability of the spinner landing on either of these items in one trial?
Go back to your sports report data. What is the likelihood of getting your best result for each drill for the next trial? (0-100%). Can you calculate the probability of each outcome/result? How and/or why/why not?
