      (Joint Probability Formula) For any two events A and B, P(A and B) = P(A) P(B| A). In English, “The probability that two things both occur (or ‘are true’) is the same as the probability that one of them occurs times the probability that the other occurs, given that the first did, indeed, occur.”
