IB Maths AA HL SL 4.6 Combined, conditional & independent events
Practise using unions, intersections, complements, conditional probability and independence with Venn diagrams, formulae and contextual events.
How this is tested
- calculate P(A ∩ B), P(A ∪ B) or P(A' | B) by choosing the correct formula or Venn diagram region
- show independence by testing whether P(A ∩ B) = P(A)P(B) or via conditional probability
- apply independence by multiplying probabilities and interpreting both events occurring
