Perhaps the most important formula in probability.Brought to you by you: http://3b1b.co/bayes-thanksThe quick proof: https://youtu.be/U_85TaXbeIoInteractive The formula for Bayes' Theorem is as follows: Let's unpick the formula using our Covid-19 example. P (A|B) is the probability that a person has Covid-19 given that they have lost their sense of smell. P (A) is the (prior) probability (in a given population) that a person has Covid-19.
