probability
How likely something
Probability measures how likely something is to happen, expressed as a number between zero (impossible) and one (certain).
In everyday speech, probability often just means likelihood: What's the probability he'll show up?
In statistics and mathematics, probability is calculated precisely—the probability of rolling a six on a fair die is one in six.
In all probability means almost certainly.
