## What is a sample space? |

In any experiment, there are certain possible outcomes; the set of all possible outcomes is called the *sample space* of the experiment. Each possible result is represented by one and only one point in the sample space, which is usually denoted by the letter S. To each element of the sample space (or to each possible outcome) a probability measure between 0 and 1 is assigned, with the sum of all the probability measures in the sample space equal to 1.
