Teaching guide

What students learn

Run repeated chance experiments and simulations with digital tools to estimate probabilities for compound events, and describe the results.

How to teach it

Order events from impossible to certain in everyday language, then quantify simple chances as fractions of the equally-likely outcomes.

Worked example
A bag has 5 counters. 5 are purple. Picking a purple counter is (impossible, unlikely, even chance, likely, certain):
Answer: certain
Why: all 5 are purple, so it always happens

Generated and checked in code, so it is correct.

Watch out for

Assuming a rare-but-possible event is impossible, and thinking past results change the next independent outcome.
