- Count outcomes and sample spaces.
- Work with single and compound events.
- Use expected outcomes and probability in context.
Worked example
A fair six-sided die has three even outcomes: 2, 4, 6. P(even) = 3/6 = 1/2 = 50%.
How the Ladder Works
Six levels run from Warm-Up to Mastery. Warm-Up has five questions; later sets grow to eight or nine depending on the topic. Clear a level with at least 80% first-try accuracy. Every level is available from the start, and retries produce fresh questions.
Hints and worked solutions support practice. Grades 7–10 is a guide, not a restriction.
