Document Summary

Probability: the chance that an uncertain event will occur (between 0 & 1) Impossible event: an event that has no chance of occurring (probability = 0) Certain event: an event that is sure to occur (probability = 1) Random experiment: an action/process that leads to one of the several possible outcomes. This list must be exhaustive (all possible outcomes must be included. The list must be mutually exclusive (no 2 outcomes can occur at the same time. Sample space: a list of all exhaustive & mutually exhaustive outcomes. Simple event: an individual outcome of a sample space. A day in january from all days in 2012. Joint event: an event described by 2+ characteristics. A day in january that is also a wednesday in 2012. Complement of an event a (denoted a): all events that are not part of event a.
