Probability notes

Probability measures how likely an outcome is. The sample space $S$ is the set of all possible outcomes. This section uses Venn diagrams to show how events combine, then applies the addition rule for…

This section teaches independent and dependent events and the multiplication rules that go with them. You will decide whether one event changes the probability of another, then compute joint…

This section uses tree diagrams (probability trees) and contingency tables to organise outcomes and calculate probabilities. You will multiply along branches, add across mutually exclusive paths…
