This worksheet teaches students to list the outcomes of chance experiments, decide whether they are equally likely, and explain whether a game is fair. The worksheet is split into warm-up questions, standard questions and then extension questions to test you.
The concepts it covers:
- An outcome is one possible result of a chance experiment. Tossing a coin has 2 outcomes: heads and tails.
- Outcomes are equally likely when each has the same chance of happening, like the numbers on a fair die.
- Outcomes are not equally likely when some have more chances, like a spinner with a bigger red section.
- A game is fair if every player has the same chance of winning.
What your child will practise:
- Listing every possible outcome of a chance experiment.
- Deciding whether outcomes are equally likely.
- Comparing likelihoods by counting the ways each outcome can happen.
- Listing outcomes of two-step experiments.
- Deciding whether a game is fair, including how to make it fair.
Every section opens with a worked example, and the download includes a full answer key with step-by-step solutions and teaching notes on the mistakes students most commonly make.
