Probability Tree Diagrams. Calculating probabilities can be hard, sometimes we add them, sometimes we multiply them, and often it is hard to figure out what to do ... tree diagrams to the rescue! 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.
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.

In experiments where there are more than two stages, or where the stages are dependent, a tree diagram is a helpful tool for systematically identifying the sample space. Tree diagrams are built by first drawing a single point (or node ), then from that node we draw one branch (a short line segment) for each outcome of the first stage.
Example: Box A contains 3 cards numbered 1, 2 and 3. Box B contains 2 cards numbered 1 and 2. One card is removed at random from each box. a) Draw a tree diagram to list all the possible outcomes. b) Find the probability that: (i) the sum of the numbers is 4. (ii) the sum of the two numbers is even.
