Webb14 dec. 2024 · Conditional probability formula The formal expression of conditional probability, which can be denoted as P (A B), P (A/B) or PB(A), can be calculated as: P (A B) = P (A∩B) / P (B), where P (B) is the probability of … Webb1 okt. 2024 · Probability can only be calculated when the event whose probability you’re calculating either happens or doesn’t happen. The event and its opposite both cannot occur at the same time. Rolling a 5 on a die, a certain horse winning a race, are examples of mutually exclusive events.
