Probability

[daodavid]

Loosely speaking,The probability conserns the study of unsertainty.
The probability can be thought of as the fraction of times an event occurs or degree of belief about occurrence of event.We then would like to use the probability to measure a chance of something occurring in an experiment.We often quantify uncertainty in Ml model for uncertainty in predictions produced by the model.Quantifying uncertainty requires the idea of random variable.which is the function that maps outcomes of random experiment to set of properties that we are interested in.Associated with the random variable is a function that measures a particular outcome will occur.This called probability distribution.

[]Probability distributions are used as a building block for many ML concepts.
