What is a probability tree?
A probability tree is a picture indicating probabilities and some conditional probabilities for combinations of two or more events. One of the easiest ways to solve a probability problem is to construct the probability tree and then read the answer.
How do you do a probability tree diagram?
A probability tree diagram is a handy visual tool that you can use to calculate probabilities for both dependent and independent events. To calculate probability outcomes, multiply the probability values of the connected branches. To calculate the probability of multiple outcomes, add the probabilities together.
What does a probability tree diagram show?
Tree diagrams are a way of showing combinations of two or more events. Each branch is labelled at the end with its outcome and the probability is written alongside the line. Two events are independent if the probability of the first event happening has no impact on the probability of the second event happening.
