Terms | Definitions |
|---|---|
 simulation | the imitation of change behavior, based on a model that accurately reflect the phenomenon under consideration |
| independent | when the results of one variable don't affect another |
| randInt(min,max,num) | randomly selects num integers from min to max |
| random | when individual outcomes are uncertain but there is a regular distribution of outcomes in a large number of repetitions |
| probability | the long-term relative frequency |
| sample space (S) | the set of all possible outcomes |
| event | and outcome of a random phenomenon, a subset of the sample space |
| probability model | a mathematical description of a random phenomenon consisting of a sample space and a way of assigning probabilities to events |
| tree diagram | enumerates each outcome in the sample space |
| Multiplication Principle | If you can do one task in n1 ways and a second task in n2 ways, then both tasks can be done in n1*n2 ways |
| sampling with replacement | when the second draw is exactly like the first |
| sampling without replacement | when you don't replace the things you select |
| disjoint | have no outcomes in common and cannot occur simultaneously |
| complement | the probability that something doesn't happen |
| union | the or of two sets |
| joint event | the simultaneous occurence of two events |
| conditional probability | the probability of one event given another |
| intersection | the and of some events |
