Conditional Probability and Independence
Videos and lessons to help High School students learn to recognize
and explain the concepts of conditional probability and
independence in everyday language and everyday situations.
For example, compare the chance of having lung cancer if you are
a smoker with the chance of being a smoker if you have lung

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.
