Probability – Experiment Approach
* A trial is an action which results in one or several outcomes.
* An event for an experiment can be described as the collection of some outcomes of the experiment.
* The empirical or experimental probability P(E) of an event E happening is given by:
– P(E) = \frac{Number \thinspace \thinspace \thinspace of \thinspace \thinspace trials \thinspace \thinspace in \thinspace \thinspace which\thinspace \thinspace the \thinspace \thinspace event \thinspace \thinspace happened}{The \thinspace \thinspace total \thinspace \thinspace number \thinspace \thinspace of \thinspace \thinspace trials}
