Author note — to cover

Decide which of two events is more likely by common denominators or decimal conversion, and order mixed lists of fractions, decimals and percentages; include events from different experiments. Both tiers. Exclude combining two events (Combined events topic) and comparing experiment against theory (comparing-with-theory, Experimental probability). (P3)

• Fluency — direct questions on comparing probabilities, 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).
