### Unit 7: Probability, Fundamental Counting Principle, Independent/dependent event

Term | Definition |
---|---|

Complementary Event | Two events in which either outcome must happen, but cannot happen at the same time; sum of the probability and its complement is 100% |

Compound Event | Two or more independent events considered together |

Counting Principle | If event M has "m" possible outcomes and event N has "n" possible outcomes, then event M followed by event N has (m*n) possible outcomes |

Dependent Event | When the outcome of one event depends on the outcome of another |

Experimental Probability | What actually happens when conducting a probability event |

Independent Event | When the outcome of one event does not affect the outcome of other events |

Outcome | A possible result in an experiment; the way an event turns out |

Permutation | An arrangement or listing of objects in which order is important |

Probability | The chance that a particular outcome will occur, measured as a ratio of the total possible outcomes |

Sample Space | The set of all possible outcomes of a random process |

Simulation | Carrying out a simple experiment to collect data |

Simple Event | An event that consists of exactly one outcome |

Theoretical Probability | What should happen when conducting a probability experiment |

Tree Diagram | A diagram shaped like a tree used to display sample space by using one branch for each possible outcome |

Uniform Probability Model | each outcome has an equal probability of happening |
