AC9M8P02 • Test
Two-event probability
Use the Skillr scratchpad or a notebook to decide whether events overlap, whether independence is stated and which probability rule applies.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
60-second Quick Read
- Mutually exclusive events have P(A and B)=0; non-exclusive events can overlap.
- For any two events, P(A or B)=P(A)+P(B)−P(A and B).
- Common trap: Multiply along a probability-tree path only when the required conditional or independence information justifies it.
