Study the following **Probability Tree Diagrams **to understand better about the probability theory using tree diagrams. This type of diagram is used in strategic decision making, valuation, or probability calculations. A probability tree has two main parts: the branches and the ends.

Take a look at the following examples of the probability tree diagram below.

Probability trees are useful for calculating combined probabilities. The probability is a measure of the possibility that any event will occur or not. This probability can be expressed using tree diagrams. Each branch is generally written on the branches, while the outcome is written on the ends of the branches. Notice that each node on the *Probability Tree Diagrams* represents an event and is associated with the probability of that event.

The tree diagram shows the outcome of any event. This is used for giving all possible possibilities which are also called the sample space. And, each leaf in the tree represents an outcome of any events. The probability that the series of events leading to a particular node will occur is equal to the product of that node and its parents’ probabilities. Remember that tree diagrams branch out and can become quite intricate.

Events may be of any type whether a single event may be a composite of more than one event. The diagrams that we provided above are the probability tree diagram.
