WebbThe set union answer comes from a discussion of lattices and probabilities (different book) where they identify join and meet with set union and intersection. So for example, (since my terminology might be wrong), they drew a lattice such as follows, {a,b} / \ {a} {b} \ / {} So in this case the join is a ∪ b. Webb12 mars 2024 · The Union Rule: P (A U B) = P (A) + P (B) – P (A ∩ B). If two events are mutually exclusive, then the probability of them occurring at the same time is P (A ∩ B) = 0. So, if A and B are mutually exclusive then the P (A U B) = P (A) + P (B) as shown in Figure 4-7. It is best to write out the rule with the intersection so that you do not ...

WebbThe probability of the intersection of independent events is: P ( A ∩ B) = P ( A) ⋅ P ( B) The probability of the intersection of dependent events is: P ( A ∩ B) = P ( A / B) ⋅ P ( B) Let's note that when the events are independent, P ( A / B) = P ( A), then the second formula in fact is always true.
