Equally Likely Outcomes and Theoretical Probability
Part of: Equally Likely Outcomes and Theoretical Probability
When outcomes are equally likely, event probability is the number of favourable outcomes divided by the total possible outcomes.
Why it matters. Probability helps compare uncertain outcomes and reason clearly about chance.
Try it in two minutes
- List the experiment's possible outcomes.
- Count outcomes that fit the event.
- Use the assumptions to calculate and interpret the chance.
Try at home. With an adult, list the equally likely results of a coin toss and compare one result's chance with its complement.
Events and Complements
Part of: Events and Complements
An event is a set of outcomes. Its complement includes all outcomes where the event does not occur, and complementary probabilities sum to one.
Why it matters. Probability helps compare uncertain outcomes and reason clearly about chance.

- List the experiment's possible outcomes.
- Count outcomes that fit the event.

Try at home. With an adult, list the equally likely results of a coin toss and compare one result's chance with its complement.
Probability Bounds and Interpretation
Part of: Probability Bounds and Interpretation
Probability lies between zero and one. It describes a chance under the experiment's assumptions; it is not a promise about a single trial.
Why it matters. Probability helps compare uncertain outcomes and reason clearly about chance.
