Webb14 feb. 2024 · Independence of A and B would therefore require that P ( A) P ( B) = P ( A ∩ B) = 0, which can only occur if at least one of the events has zero probability. Thus, Wasserman is correct to assert that if the events are disjoint, with positive probability, they cannot be independent. milly beddingIn probability theory, conditional dependence is a relationship between two or more events that are dependent when a third event occurs. For example, if and are two events that individually increase the probability of a third event and do not directly affect each other, then initially (when it has not been observed whether or not the event occurs) milly berroneWebbProbability is simply how likely something is to happen.
