Tree diagrams are a helpful tool for calculating probabilities when there are several independent events involved. They get their name because these types of diagrams resemble the shape of a tree. The branches of a tree split off from one another, which then in turn have smaller branches A probability tree diagram shows all the possible events. The first event is represented by a dot. From the dot, branches are drawn to represent all possible outcomes of the event. The probability of each outcome is written on its branch Instructions: Use this step-by-step Total Probability Rules calculator to compute the probability of an event \(A\), when you know the conditional probabilities of \(A\) with respect to a partition of events \(B_i\). Please type in the conditional probabilities of A with respect to the other events, and optionally, indicate the name of the conditioning events in the form below In mathematics, the tree diagram is used in probability and statistics and it allows us to calculate the number of possible outcomes of an event where those outcomes are listed in an organised manner.
