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.
