Conditional Probability and Tree Diagrams | Year 2 Stats | A Level Maths

Tree diagrams are particularly well suited to multi-stage probability problems with conditional probabilities. In this lesson you will learn how to construct a tree diagram with conditional branches, multiply along branches and add across branches to find probabilities of compound events, apply the conditional probability formula to read off conditional probabilities, and critique modelling assumptions where appropriate.
