Conditioning on zero probability event
WebAssuming that A and B are events with nonzero probabilities, P (A B) = P (A) is actually mathematically equivalent to P (B A) = P (B). We can see this because P (A B) = P (A) means P (A and B)/P (B) = P (A) from definition of conditional probability, P (B A) = P (B) means P (A and B)/P (A) = P (B) from definition of conditional probability, and WebMar 27, 2024 · The conditional probability of A given B, denoted P ( A ∣ B), is the probability that event A has occurred in a trial of a random experiment for which it is …

Definition Let be some … WebDec 7, 2024 · Conditional Probability for Mutually Exclusive Events. In probability theory, mutually exclusive events are events that cannot occur simultaneously. In other words, …
On the discrete level, conditioning is possible only if the condition is of nonzero probability (one cannot divide by zero). On the level of densities, conditioning on X = x is possible even though P ( X = x ) = 0. This success may create the illusion that conditioning is always possible. Regretfully, it is not, for several reasons presented below. The result P ( Y ≤ 0.75 X = 0.5 ) = 5/6, mentioned above, is geometrically evident in the followi… WebIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event.
