What you’ll learn to do: use tree and Venn diagrams to calculate probabilities

Let’s say that you flipped a coin three consecutive times.  What is the probability of getting two or more heads Drawing a tree diagram would help in this situation. It would allow us to see the various possibilities for consecutive independent events. Venn diagrams are another way to organize information from a probability problem. Venn diagrams allow us to see what events are not mutually exclusive. Those events appear in the overlap of the circles of a Venn diagram.
