Author note — to cover

The formula favourable outcomes over total outcomes for fair dice, coins, spinners, counters and cards, with answers as simplified fractions and optionally decimals or percentages. Stress the equally-likely precondition. Both tiers. Exclude two-event experiments (sample spaces, Diagrams topic) and estimates from data (Experimental probability). (P2, P7)

• Fluency — direct questions on probability from equally likely outcomes, 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).
