| Outcome | A result of a probability experiment. |
| Probability | the chance of something occurring. |
| Sample Space | The set of all possible outcomes. |
| Simple Event | one event or action |
| Impossible | A probability of 0 |
| Certain | A probability of 1 |
| Equally likely as not | A probability of 1/2 |
| Likely | A probability between 1/2 and 1 |
| Unlikely | A probability between 0 and 1/2 |
| experiment | Something you can do over and over again, and you don’t know what will happen each time. |
| Complementary Events | Two events in which either one of the other must happen, but they cannot happen at the same time. |
| Event | The desired outcome or set of outcomes in a probability experiment. |
| Experimental Probability | An estimated probability based on the relative frequency of positive outcomes during an experiment. It is based on what ACTUALLY occurred during such an experiment. |
| Theoretical Probability | 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. |
| Likelihood | The chance of an event happening. |
| Relative Frequency | A ratio that compares the frequency of each category to the total. |
| Relative Frequency Bar Graph | A bar graph showing the relative frequency of an experiment. |
| Relative Frequency Table | A list of the relative frequencies in an experiment. |
| Uniform Probability Model | A probability model which assigns equal probability to all outcomes. |
