| Term | Definition |
|---|---|
| complementary event | two events in which one or the other can happen, but not at the same time. the sum is 1 or 100% |
| compound event | a event consisting of two or more simple events. |
| event | the desired outcome of outcomes in a probability experiment |
| experimental propability | a estimated probability based on relative frequency of positive outcomes happening during a experiment. It is based on what actually happened during a expieriment |
| likelihood | the chance of a event happening |
| outcome | any of the possible results of an action |
| probability | the chance some event will happen. |
| probability expieriment | when you perform a event to find the likelihood of the 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 to a total |
| relative frequency table | a table used to organize occurrences to a total |
| sample space | the set of all possible outcomes in a probability expieriment |
| simple event | one outcome or a collection of outcomes |
| simulation | a expieriment designed to model the action of the situation |
| theoretical probability | the ratio of the number of ways an event can occur to the number of possible outcomes. it is based on what should happen. |
| theoretical probability of compound event | the ratio of way a event can happen to the number of possible outcomes in the sample space. |
| tree diagram | a diagram used to show the sample space. |
| uniform probability model | a probability model used to show which assignes equal probability to all outcomes. |
