| Theoretical probability | Write the number of way the event can occur by the total number of likely outcomes |
| Sample space | All the possible outcomes of an experiment |
| Compound event | More than one event happening at the same time |
| Counting principle | Multiply the number of outcomes together |
| Disjoint events | Events that cannot happen in the same trial |
| Independent events | When one event does not effect on another event |
| Dependent events | When event does have an effect on another event |
| Prediction | A guess about something in the future |
| Random | Doing something without looking |
