Possibility And Tree Diagrams
Bayani Gaba-gaba
When events happen one after another, a tree diagram lays out every possible path and its probability. Multiplying along the branches and adding the relevant paths turns a tangled problem into clear, step-by-step arithmetic.
In this lesson you will use possibility (sample space) diagrams and tree diagrams, including successive selection with or without replacement.

Tree and Venn Diagrams
Sometimes, when the probability problems are complex, it can be helpful to graph the situation. Tree diagrams and Venn diagrams are two tools that can be used to visualize and solve conditional probabilities. A tree diagram is a special type of graph used to determine the outcomes of an experiment.
