Video lessons with examples and solutions to help High School students
learn to find the conditional probability of *A* given *B* as
the fraction of *B*ӳ outcomes that also belong to *A*, and
interpret the answer in terms of the model.

- Find and interpret conditional probabilities using a two-way table, Venn diagram, or tree diagram.
- Understand the difference between compound and conditional probabilities.
