Sample Space

Pronunciation: /ˈsɑm pəl speɪs/ ?

A sample space consists of all possible outcomes of an experiment.

For example, when we flip a coin, there are two possible outcomes: heads and tails. The sample space is then heads and tails. The size of the sample space is 2.

The probability of the sample space is always 1, meaning that there is exactly 100% probability of something in the sample space occurring during the experiment.
