Probability of Simple Events
Term | Definition |
---|---|
Probability | The measure of how likely the event is to occur. |
Experiment | An activity involving chance. |
Trial | Each repetition or observation of an experiment. |
Outcome | The result of a trial. |
Event | A set of one or more outcomes. |
Likely | An event that has a probability to occur more than 1/2, but less than 1. |
Unlikely | An event that has a probability to occur more than 0, but less than 1/2. |
Certain | An event that has a probability of 1 to occur, or 100%. |
Impossible | An event that has a probability of 0 to occur. |
As Likely As Not | An event that has a probability of 1/2 to occur, or 50%. |
Theoretical Probability | Used to find the probability of an event when all outcomes are equally likely. This is used to make predictions BEFORE performing an experiment. |
Complement | The set of all outcomes that are NOT the event. |
Experimental Probability | The probability of an event based on what has already happened. |
Independent Events | the result of the second event is not affected by the result of the first event. |
Dependent Events | the probability of one event occurring influences the likelihood of the other event. |
