Tree Diagram: Explanation & Examples. A tree diagram represents the hierarchy of the events that need to be completed when solving a problem. The tree diagram starts with one node, and each node has its branches that further extend into more branches, and a tree-like structure is formed.
Here is a tree diagram for the toss of a coin: There are two "branches" (Heads and Tails) The probability of each branch is written on the branch. The outcome is written at the end of the branch. We can extend the tree diagram to two tosses of a coin: How do we calculate the overall probabilities? We multiply probabilities along the branches.
Using a Tree Diagram to Identify a Sample Space. Use a tree diagram to find the sample spaces of each of the following experiments: You flip a coin 3 times, noting the outcome of each flip in order. You flip a coin. If the result is heads, you roll a 4-sided die. If it’s tails, you roll a 6-sided die.
Tree diagram probability is a way of organizing the information for two or more probability events. Probability tree diagrams show all the possible outcomes of the events and can be used to solve probability questions. A simple tree diagram has branches that match each outcome.

If the result is heads, you roll a 4-sided die. If it’s tails, you roll a 6-sided die. You are planning to go on a hike with a group of friends.
Although tree diagrams can be tedious to construct, they are useful for organizing a sequence of events and probabilities in a clear and simple manner. Below is an example of a basic tree diagram with one event (the flip of a coin) and the probabilities of its two outcomes, heads or tails:
