A chance experiment is made of up of a number of trials. An outcomeis the observation you obtain from one trial. The sample space contains all possible outcomes: it"s usually denoted s, it"s a set, it"s an event. (often denoted e, events are subsets of the sample space, outcomes are elements of the sample space.
