Teaching guide
Recognise that complementary events have probabilities that add to one, and use this to calculate probabilities in real contexts.
Order events from impossible to certain in everyday language, then quantify simple chances as fractions of the equally-likely outcomes.
Generated and checked in code, so it is correct.
Assuming a rare-but-possible event is impossible, and thinking past results change the next independent outcome.
