Grade 7 — Understand that the probability of a compound event is the fraction of outcomes in the sample space for which the event occurs.
The skill that covers it
What a student should be able to do
- Find the probability of a two-stage event with replacement.
- Adjust both the numerator and the denominator when there is no replacement.
- Read a probability off an organised list or a two-way table of a sample space.
- Handle an "at least one" compound event through its complement.
