Description |

Introduction to Probability | To introduce probability theory through simple experiments. To use the formula for finding the probability of an event. To find the probabilities of events with equally likely and non-equally likely outcomes. |

Certain and Impossible Events | To understand the theory behind certain and impossible events. To classify experiments accordingly. To compute related probabilities. |

Sample Spaces | To determine the sample space of an experiment by examining each possible outcome. |

The Complement of an Event | To define and identify the complement of an event. To find related probabilities. |

Mutually Exclusive Events | To understand the theory behind mutually exclusive and non-mutually exclusive events. To classify an experiment accordingly. Venn diagrams and other visuals are used. |

Addition Rules for Probability | To find the probability of mutually exclusive events by applying the addition rule. |

Independent Events | To understand the theory behind independent events. To use the multiplication rule to compute related probabilities. |

Dependent Events | To understand the theory behind dependent events. To use a modified version of the multiplication rule to compute related probabilities. |

Conditional Probability | To understand the theory behind conditional probability. To derive the formula for finding conditional probabilities, and to compute related probabilities. |
