SL 4.6—Combined, conditional and independent events Topic Practice
SL 4.6—Combined, conditional and independent events Topic Practice
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
