We also take the liberty in stating some theorems without presenting proofs and emphasize that the contents of this chapter, by no means, represent all topics of probability that deserve a detailed discussion.

A chance or random experiment is an experiment whose outcomes or results of its performance are uncertain. A set of outcomes is called an event. The set of all possible outcomes is referred to as the sample space, denoted by c01-math-0001. Thus, an event is a subset of the sample space and an element of the sample space is a sample point.

Two events c01-math-0002 and c01-math-0003 are referred to as mutually exclusive if their intersection is empty. A set c01-math-0004 is called a partition of c01-math-0005 if the events c01-math-0006 are mutually exclusive, such that .
