AC9M9P03 • Test
Simulations and repeated chance experiments
Use the Skillr scratchpad or a notebook to divide event counts by total trials, compare with and without replacement, and organise compound outcomes.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
60-second Quick Read
- Digital simulations estimate probability using relative frequency: event count divided by total trials.
- With replacement keeps probabilities the same; without replacement changes later probabilities.
- Common trap: Simulation estimates may be close to theoretical probabilities, but they do not have to match exactly.
SkillrHub Test guide
Use this short shuffled test set to check the skill, read feedback and review missed items. Repeat quiz practice to access more of the full question bank over time.
- Worked example: Before answering, classify what the question gives, what it asks for, and which curriculum idea links them. For Simulations and repeated chance experiments, explain the evidence or method in one complete sentence before selecting the final answer.
- Common mistake: Do not match answers by familiar wording only. Check the full AC9M9P03 idea, the units or evidence, and any exception in the stem.
- Assessment guidance: Use this short shuffled set for one attempt. Repeat quiz practice to get access to more of the full question bank over time.
- SkillrHub review path: Use feedback to name the misconception, practise a corrected example, and retest only after you can justify the answer aloud.
