| probability | The chance an event will occur (# possible/total) |
| mutually | Events are **** exclusive if they CAN'T occur at the same time |
| complement | All outcomes are DIFFERENT from the favorable outcome |
| equally | If an outcome has the SAME chance of occurring |
| impossible | An event with a probability of 0 (zero) |
| independent | The outcome of a 2nd event does NOT depend on the first event |
| dependent | If one outcome AFFECTS the second |
| experiment | Testing probability; leads to results called OUTCOMES |
| outcome | Result of an experiment |
| event | Possible set of outcomes for an experiment |
| sample | Set of ALL possible outcomes for an experiment |
| conditional | An event occurs IF another event also occurs |
