Author note — to cover

Set the relative frequency of an event beside its theoretical probability using common denominators or decimals, and describe the gap in context. Question types: whose results sit closer to theory, do these results support fairness. Both tiers. The fairness verdict itself is detecting-bias; the effect of more trials is effect-of-sample-size. (P3, P5)

• Fluency — direct questions on comparing experimental and theoretical probability, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
