When A and B are independent, P (A and B) = P (A) * P (B); but when A and B are dependent, things get a little complicated, and the formula (also known as Bayes Rule) is P (A and B) = P (A B) * P (B). The intuition here is that the probability of B being True times ...
WebThe probability mass function, P ( X = x) = f ( x), of a discrete random variable X is a function that satisfies the following properties: P ( X = x) = f ( x) > 0, if x ∈ the support S. ∑ x ∈ S f ( x) = 1. P ( X ∈ A) = ∑ x ∈ A f ( x) First item basically says that, for every element x in the support S, all of the probabilities must ...
