Webb1 Answer Sorted by: 2 Here is a counter-example for your second equation, where you replace ∩ s with ∪ s. Suppose that P r ( R ∪ E) = 1 / 2, with P r ( R ∩ E) = 1 / 6, and P r ( R) = P r ( E) = 1 / 3. And suppose that B = ( R ∪ E) c, so P r ( B) = 1 / 2, with P r ( B ∩ R) = P r ( B ∩ E) = 0. Calculating all the terms in the second formula, we have: 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 ...
