Year 7 Chance
Experimental Probability — Carnival Games
Probabilities from real results: frequency tables, fractions and finding the spinner that fits the data.
30 questions · one per page
Probability from data, not guesses.
The Riverfair carnival is in town and every stall has been tested — dice rolled, wheels spun, ducks drawn. Theoretical probability uses equally likely outcomes; experimental probability uses what actually happened. Every section starts with the method, and a later step only appears after the current step is correct.

Experimental probability = favourable outcomes ÷ total trials. Q1–20 read frequency tables of finished experiments. Q21–30 hand you the results and ask which spinner could have produced them — the sectors must roughly match the frequencies.

Experimental probability, mastered.
The student has turned frequency tables into probabilities, simplified, used complements and combined events, predicted future results, and matched spinners to their data.
