If I flip a coin, what’s the probability of the coin landing on tails?

Sample Space |
---|
A sample space is a collection of all possible outcomes. |
The coin can land on either heads or tails. There is a 1 / 2 = .50 (50%) chance of the coin landing on tails.
Probabilities will always be between 0 (0%) and 1.00 (100%).
Impossible Events |

An event with a probability of 0 is impossible (it will never occur). |
Certain Events |

An event with a probability of 1 is certain (it will always occur). |
