| tree diagram | A tree-like diagram on which each branchshows a possible outcome of a situation |
| counting principle | If a situation can occur in m ways, and a second situation can occur in n ways, then these things can occur together in m X n ways. |
| experiment | In probability, any activity involving chance, like a coin flip. |
| outcomes | One of the possible equally likely results of an experiment. |
| sample space | The set of all possible outcomes of an experiment. |
| event | A set of outcomes. |
| probability | The chance that a particular event can occur. |
| theoretical probability | The actual probability of an event. The ratio of the number of equally likely outcomes in the event to the number in the sample space. |
| experimental probability | An estimated probability based on data from experiments or surveys. |
| trial | One experiment. |
| geometric probability | A probability based on comparing measurements of geometric figures. |
| conditional probability | The probability that an event B will occur, given that event A has already occurred. |
| compound event | Event containing more than one outcome. |
| independent event | Evnets for which the occurence of one has no effect on the probability of the other. |
| dependent event | Events for which the occurrence of one affects the probability of the other. |
