Section 7. 1 – Experiments, Sample Spaces, and Events 1 Section 7.1 Experiments, Sample Spaces, and Events An experiment is an activity with observable results (outcomes). A sample point is an outcome of an experiment. A sample space is a set consisting of all possible sample points of an experiment. A Finite Sample Space is a sample space with finitely many outcomes. An event is a subset of a sample space of an experiment. Since an event is defined in terms of a set, it should make sense that we will use what we covered in Chapter 6 in our study of experiments and events. The union of two events E and F is F E . The intersection of two events E and F is F E . If the intersection of two events E and F is equal to the Ø, then E and F are called mutually exclusive . Two events that can not happen at the same time are mutually exclusive. Example: A box contains 1 red, 1 blue and 1 white card. If you pick one card from the box, the possible outcomes are: Sample Space: {R, B, W} The event R: the chosen card is Red.
