Informal Definition
The probability of an event is the likelihood that the event will occur (within a certain formally or informally understood context).
As such, a probability can range from $0$ (will never happen) to $1$ (is certain to happen).
Commonly, a probability is often stated in terms of a percentage.
Formal Definition
Let $\EE$ be an experiment.
Let $A \in \Sigma$ be an event in the event space $\Sigma$ of $\EE$.
Let $\Pr$ be the probability measure of $\EE$.
Then the probability of $A$ is the value $\map \Pr A$.
