 * __Probability__**

//Definition.//

Probabilities are a branch of mathematics that is dedicated to the study of certain so-called randomized experiments, ie coming from the random, which we know all the possible outcomes, but can’t be sure of what will be the  exact outcome of the experiment.

//Description.//

The probability is measured by a number between 0 and 1, if an event never occurs its probability is 0, while if the event occurs its probability is 1. Thus, the odds usually come expressed as fractions or percentages.
