| Term | Definition |
|---|---|
| binomial distribution | a type of probability distribution that shows the probabilities of the outcomes of a binomial experiment |
| binomial experiment | an experiment in which there are fixed numbers of independent trials, exactly two possible outcomes for each trial, and the probability of success is the same for each trial |
| combination | selections of objects in which order is not important |
| compound event | the union or intersection of two events |
| conditional probability | the probability that event B occurs, given that event A occurred; written at P(B|A) |
| conditional relative frequency | the ratio of a joint relative frequency to the marginal relative frequency |
| dependent events | two events in which the occurrence of one event does affect the occurrence of the other event |
| disjoint/mutually exclusive events | two events that have no outcomes in common |
| event | a collection of one or more outcomes |
| experimental probability | the ratio of the number of successes, or favorable outcomes, to the number of trials in a probability experiment |
| Fundamental Counting Principal | a way to find the total number of possible outcomes |
| geometric probability | a probability found by calculating a ratio of two lengths, areas, or volumes |
| independent events | two events in which the occurrence of one event does not affect the occurrence of another event |
| joint frequency | each entry in a two-way table |
| joint relative frequency | the ratio of a frequency that is not in the "total" row or the "total" column to the total number of values or observations |
| marginal frequency | the sums of the rows and columns in a two-way table |
| marginal relative frequency | the sum of the joint relative frequencies in a row or a column |
| n factorial | the product of the integers from 1 to 'n', for any positive integer 'n' |
| outcome | the possible results of an experiment |
| overlapping events | two events that have one or more outcomes in common |
| permutation | an arrangement of objects in which order is important |
| probability distribution | a function that gives the probability of each possible value of a random variable |
| probability experiment | an action, or trial, that has varying results |
| probability of an event | a measure of the likelihood, or chance, that an event will occur |
| random variable | a variable whose value is determined by the outcomes of a probability experiment |
| sample space | the set of all possible outcomes for an experiment |
| simulation | the use of a model to reproduce the conditions of a situation or process so that the simulated outcomes closely math the real-world outcomes |
| theoretical probability | the ratio of the number of favorable outcomes to the total number of outcomes when all outcomes are equally likely |
| two-way table | a frequency table that displays data collection from one source that belong to two different categories |
