The formula for conditional probability is: P (B A) = P (A and B) / P (A) which you can also rewrite as: P (B A) = P (A∩B) / P (A) Need help with homework?
WebbThere’s a couple of different formulas, depending on if you have dependent events or independent events. Formula for the probability of A and B ( independent events): p (A and B) = p (A) * p (B). If the probability of one event doesn’t affect the other, you have an independent event. WebbProbability Formulas. Probability = (Number of a Favourable outcome) / (Total number of outcomes) P = n (E) / n (S) Where P is the probability, E is the event and S is the sample space. Now, let’s looks at some very …
