Normal Size Small Size show me how
|likelihood of an event happening
|one of the possible results of an experiment
|set of one or more outcomes
|any activity with an observable result
|An event will definitely happen. 100% or 1.0 probability
|An event will equally likely happen or not happen. 50% or .5 probability
|An event will definitely not happen. 0% or 0 probability
|An event is more likely to happen than not happen. 51-99% or 0.51-.99 probability
|An event is less likely to happen than to happen. 1-49% or 0.01-.49 probability
|An experiment done one time
|the ratio of the number of times an event occurs to the total number of trials or times the activity is performed
|what you would expect to happen in an experiment without actually doing it.
|set of all possible outcomes for an experiment
|Each outcome is equally likely
|Each outcome is not equally likely
|More than one event occurring.
|A way to show to all possible outcomes with the events branching off from event to another.
