Probability
| Term | Definition |
|---|---|
| combination | an arrangement, or listing, of objects in which order is not important |
| complementary events | the events of one outcome happening and that outcome not happening / the sum of these events are 1 |
| compound events | an event consisting of two or more simple events |
| dependent events | two or more events in which the outcome of one event affects the outcome of the other event |
| experimental probability | an estimated probability based on the relative frequency of positive outcomes occurring during an experiment |
| factorial | the expression n! is the product of all the counting numbers beginning with n and counting backward to 1 |
| fair game | a game in which players of equal skill have an equal chance of winning |
| Fundamental Counting Principle | uses multiplication of the number of ways each event in an experiment can occur to find the number of possible outcomes in a sample space |
| independent events | two or more events in which the outcome of one event does not affect the outcome of the other event |
| outcome | one possible result of a probability event |
| permutation | an arrangement, or listing, of objects in which order is important |
| probability | the chance that some event will happen / it is the ratio of the number of ways a certain event can occur to the number of possible outcomes |
| random | outcomes that occur when each outcome is equally likely to occur |
| sample space | the set of all possible outcomes of a probability experiment |
| simple event | one outcome or a collection of outcomes |
| theoretical probability | the ratio of the number of ways an event can occur to the number of possible outcomes |
| tree diagram | a diagram used to show the total number of possible outcomes in a probability experiment |
