Terms | Definitions |
|---|---|
 Outcomes | when you perform an experiment, the probbible results are called outcomes |
| Event | is a collection of outcomes |
| favorable outcomes | once you specifiy an event, the outcomes for that event are called favorable outcomes |
| Sample Space | The set of all possible outcomes. |
| Tree Diagram | You can represent a sample space by using an organized list, or a table. |
| Two-Stage Experiment | An experiment with two stages or events. |
| Multi-Stage Experiment | Experiments with more than two stages. |
| Fundamental Counting Principle | Used to find the number of possible outcomes. |
| Permutation | An arrangement of objects in which order is important. |
| Factorial | The product of the positive integers less than or equal to n. |
| Circular Permutation | Objects are arranged in a circle or loop. |
| Combination | An arrangement of objects in which order is not important. |
| Geometric Probability | Probability that involves a geometric measure such as length or area. |
| Probability Model | a mathematical model used to match a random phenomenon. |
| Simulation | The use of a probability model to recreate a situation again and again so that the likelihood of various outcomes can be estimated. |
| Random Variable | A variable that can assume a set of values, each with fixed probabilities. |
| Expected Value | Also known as mathematical expectations, is the average value of a random variable that one expects after repeating an experiment. |
| Compound Event | Consists of two or more simple events. |
| Independent Events | If the probability that A occurs does not affect the probability that B occurs. |
| Dependent Event | If the probability that A occurs in some way changes the probability that B occurs. |
| Conditional Probability | The notation P (B/A) is read the probability that event B occurs given that event A has already occurred. |
| Probability Tree | A tree diagram with possibilities. |
| Mutually Exclusive | If the two events cannot happen at the same time. |
| Complement | Consists of all the outcomes in the sample space that are not included as outcomes of event A. |
| Network | A collection or vertices, called nodes, and segments called edges that connect the nodes. |
| Traceable Network | All of the nodes are connected, and each edge is used once in the network. |
