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 |
