My entire Unit on Probability is now online! The interactive spinners and die rolls are truly random. This unit includes lessons on the following topics:

- Introduction to Probability covers experiments, outcomes, events and probabilities.
- Certain and Impossible Events presents examples and probabilities for each type of event.
- Sample Spaces covers all possible outcomes for experiments with marbles, playing cards and more.
- Complement of an Event computes the probability that an event will not occur.
- Mutually Exclusive Events examines experiments to determine if they have any outcomes in common.
- Addition Rules are used to compute the probabilities of events that are, and are not, mutually exclusive.
- Independent Events computes the probability of independent events that occur in sequence.
- Dependent Events computes the probability of dependent events, accounting for outcomes common to both.
- Conditional Probability provides step-by step examples for computing conditional probabilities.
- Practice Exercises are 10 additional problems for assessment of skills and knowledge.
- Challenge Exercises are 10 additional real-world problems to challenge students.
