Probability is a measure of the chance that an outcome or an event may
occur, in the same way that length is a measure of the magnitude of an
object.
In particular, probability is defined on the framework of events
that consists of:
-
•
the outcomes of an experiment (the elements of a set) ;
-
•
the sample space which is the list of all these outcomes (the
universal set) ;
-
•
the events, collections of outcomes (subsets of the sample
space).
