Conditional Probability & Tree Diagrams




Conditional Probability with a Tree Diagram
This is an example of a typical tree diagram problem involving conditional probability. It also reviews the idea of a false positive and a false negative.

Tree Diagram and Conditional Probability Example
In this video, we look at how to use tree diagrams to solve conditional probability questions. We use a few examples to solve some worded conditional probability problems that will require us to draw tree diagrams.
