This worksheet can be used by students who have just been taught how to draw and complete a Probability tree diagram. I have a PowerPoint containing worked examples, which I use with this worksheet.

This is a whole lesson on Tree diagrams but there is probably (pun intended) enough material for two lessons. The lesson is designed as the first lesson, so concentrates on more basic tree diagrams ...

👉 Learn how to find the conditional probability of an event. Probability is the chance of an event occurring or not occurring. The probability of an event is given by the number of outcomes divided ...

For any event that has multiple outcomes with different probabilities, it can be helpful and illustrative to construct a chart or diagram of the possible outcomes. Tree diagrams are a useful example ...

The sum of the probabilities of all outcomes is 1. Independent events are those not affected by a previous event. The probability of two independent events both happening is 𝑃(A and B) = 𝑃(A) × 𝑃(B ...
