Term | Definition |
biased | a sample space in which one or more outcomes are favored (not fair) |
complementary event | the compliment of an event E are all the outcomes in the sample space that are not in event E |
event | a collection of outcomes from an activity (favorable outcomes make an event happen |
experimental probability | a probability based on data collected or observations made in an experiment |
fair | an experiment in which the probability of each outcome is the same |
mutually exclusive | two events that cannot happen at the same time |
non-uniform probability model | a probability model in which the outcomes do not necessarily have equal probabilities |
observed frequency | the number of observations of a data value in an experiment |
outcomes | all the possible results of an activity |
probability | a description of how likely an event is to occur |
probability distribution | a table or a graphical display presenting all the outcomes of the sample space and their probabilities |
probability model | a model that represents a sample space of outcomes, events, and the probabilities of these outcomes and events |
relative frequency | the ratio of the observed frequency of a data value to the total number of observations in a chance process |
sample space | the collection of all possible outcomes from an activity |
theoretical probability | the ratio of the number of favorable outcomes to the total number of possible outcomes |
uniform probability model | a probability model in which all the outcomes have an equal probability of occurring |
venn diagram | a diagram that uses circles to represent relationships for simple events |
