# Data Science concepts in 5 minutes: Probability, Statistics and Bayes’ theorem.

In this quick post I go through how Bayes’ theorem uses conditional probability and statistic to evaluate the probability of an event based on prior knowledge and conditions that might be relevant to that event. Many modern machine learning techniques rely on this formula so I have sprinkled links to other sources through out the post. Highly encourage you to check these links out as they’re great explanations of complex ideas — some are even interactive!
