# 2-Sided Coin Toss Experiment

A 2-Sided Coin Toss Experiment is a k-sided coin toss experiment where *k*=2 (with symbols {H,T}).

**AKA:**Coin Flipping.**Context:**- It can be a Binomial Experiment (it has Sample Space of Two Random Experiment Outcomes in the Outcomes are Independent).
- It can range from being an Unbiased Coin Toss Experiment to being an Biased Coin Toss Experiment.
- It can be associated with a Coin Toss Trial (e.g. {{H,T,H}, {H,T,T}, {T,T,H})

**Example(s):**- Toss a coin one time, with:
- Sample Space={{H},{T}}.
- Event Space={{},{H},{T},{H,T}})

- Toss a coin two consecutive times, with:
- Sample Space={(H,H),(T,T),(H,T),(T,H)}
- Event Space={{},{(H,H)},{(T,T)},{(H,T)},{(T,H)},{(H,H),(T,T)},{(H,T)(T,H)} … {(H,H),(T,T),(H,T),(T,H)} with 2
^{4}Events.

- Toss a coin three consecutive times, with:
- Sample Space with 8 possible Outcomes.
- Event Space with 256 possible Events.

- Toss a coin one time, with:
**Counter-Example(s):**- a Sequential Random Experiment, such as: Toss a coin two consecutive times, and roll a dice two times.
- a Dice Roll Experiment
