| Question | Answer |
|---|---|
| complementary event | two events in which either one or the other must happen, but they cannot happen at the same time. the sum of the probabilty of an event and its complement is 1 or 100% |
| compund event | an event consisting of two or more simple events |
| event | the desired outcome or set of outcomes in a probability experiment |
| experimental probablity | An estimated probability based on the relative frequency of positive outcomes occurring during an experiment. It is based on what actually occurred during such an experiment. |
| likelihood | The chance of an event occurring. |
| outcome | Any one of the possible results of an action. For example, 4 is an outcome when a number cube is rolled. |
| probablity | The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number of possible outcomes. |
| probablity experiment | When you perform an event to find the likelihood of an event. |
| relative frequency | A ratio that compares the frequency of each category to the total. |
| relative frequency bar graph | A graph used to organize occurrences compared to a total. |
| relative frequency table | A table used to organize occurrences compared to a total. |
| sample space | The set of all possible outcomes of a probability experiment. |
| simple event | One outcome or a collection of outcomes. |
| simulation | An experiment that is designed to model the action in a given situation. |
| theoretical probablity | The ratio of the number of ways an event can occur to the number of possible outcomes in the sample space. It is based on what should happen when conducting a probability experiment. |
| theoretical probability of a compund event | The ratio of the number of ways an event can occur to the number of possible outcomes in the sample space. It is based on what should happen when conducting a probability experiment. |
| tree diagram | A diagram used to show the sample space. |
| uniform probability model | A probability model which assigns equal probability to all outcomes. |
