Statistics and modelling 3.3 Solve straightforward problems involving probability
Key tips
- Revise 2.6 Probability skills.
- Questions may be set in real-life contexts.
- The solution of problems will involve a selection of techniques from:
- theoretical and experimental probability
- tree diagrams
- Venn diagrams
- permutations and combinations.
- Make sure you understand the differences between ‘mutually exclusive’, ‘independent’, and ‘complementary’.
- The use of sigma notation (PDF 224KB) may be required, for example, in calculations or proofs.
- The use of appropriate technology is expected.
- Excellence questions may require the use of probabilities from any of the binomial, Poisson, and normal distributions.
