Document Summary
The probability is a measurement of the chance. The probability is a number between 0 and 1, corresponding to 0% and 100% Experiment a process (game) that lead to an outcome as observation that cannot be predicted. (i. e. random outcome) Sample point the most basic outcomes of an experiment. The sample points must be mutually exclusive from each other. Sample space the collection of all possible sample points. Event a specific collection of sample points which have a common property. An event can be a subset of the sample space. The sample is also an event: impossible event the event that won"t happen ever. This will be an empty set that contains no sample points: certain event the event that will happen for sure. Events: capital letters such as a, b, c : a = {event description} Probability: p: p(a) = probability / chance that a will happen. The probability is a number measuring the chance.
