A Countable Sample Space is a Sample Space that is a Countable Set.

**AKA:**Discrete Sample Space.**Context:**- It can be:
- It can be a Finite Sample Space.
- …

**Example(s):**- any Finite Sample Space, such as:
- {Heads,Tails}, the Sample Space of a Coin Toss Experiment.
- {1,2,3,4,5,6}, the Sample Space of a Dice Roll Experiment.

- the Sample Space for the Coin Toss Experiment where the Coin is tossed until a Heads shows up (because the coin could be tossed indefinitely).
- …

- any Finite Sample Space, such as:
**Counter-Example(s):**- The Time Duration [0, ∞) of a Lifetime Experiment, such as how long a Lightbulb will last.
- The Scale of person Heights.

**See:**Continuous Sample Space.
