The notation p(a ∩ b) represents the probability that both events A and B occur simultaneously. This concept is crucial in understanding how two events interact with each other, particularly in the context of independence and conditional probability. When analyzing events, knowing p(a ∩ b) helps to determine the likelihood of their joint occurrence, which can provide insights into the relationship between these events.
congrats on reading the definition of p(a ∩ b). now let's actually learn it.
