IB Maths AI SL 4.6 Combined, conditional & independent events
Students practise calculating combined, conditional, and independent probabilities using tables, tree diagrams, and product rules—especially with sampling without replacement.
How this is tested
- find conditional probability from a two-way table using the correct subset
- use the multiplication rule for dependent events without replacement
- determine independence by verifying P(A ∩ B) = P(A) × P(B) using tabulated probabilities
