Tree Diagrams
Each branch of a tree diagram places the probability together with its respective possible outcome.
The end of each branch has a node which can start new branches depending on the possibile outcomes.
Keep in mind that the sum of probabilities of the branches of each node is 1.
Examples
A class consists of six girls and 10 boys. If a committee of three is chosen at random, find the probability of:
1 Three boys being chosen.
2Exactly two boys and a girl being chosen.
3Exactly two girls and a boy being chosen.
4 Three girls being chosen.
