Probability Vocab
| Question | Answer |
|---|---|
| An activity involving chance, such as tossing a coin | experiment |
| Each repetition or observation of an experiment | trial |
| A possible result of a probability experiment | outcome |
| A set of one or more outcomes | event |
| A measure from 0 to 1 (or 0% to 100%) that describes how likely an event is to occur | probability |
| The set of all outcomes that are Not the event. | complement |
| The ratio of the number of times an event occurs to the total number of trials, or times that the activity is performed | experimental probability |
| All possible outcomes of an experiment | sample space |
| States that you can find the total number of outcomes for two or more experiments by multiplying the number of outcomes for each separate experiment. | Fundamental Counting Principle |
| The ratio of the number of equally likely outcomes of an event to the total number of possible outcomes | theoretical probability |
| Events for which the outcome of one event does not affect the probability of the other | independent events |
| Events for which the outcome of one event affects the probability of the second event | dependent events |
