WebThe mathematical notation that is used to represent the union between two sets is '∪'. This operator is called infix notation and it is surrounded by the operands. Consider two sets P and Q, where P = {2,5,7,8} and Q = {1,4,5,7,9}. P ∪ Q = … WebJan 27, 2024 · (1) P ( A ∣ B) = P ( A ∩ B) P ( B) and so if we condition everything on C having occurred, we get that (2) P ( A ∣ ( B ∩ C)) = P ( ( A ∩ B) ∣ C) P ( B ∣ C) which is the result that puzzles and surprises you; you think it should be P ( A ∣ ( B ∩ C)) = P ( A ∩ B ∩ C) P ( B ∩ C).

Web10. You are basically correct. P (A B) is the probability of A given B. P (A B, C) is the probability of A given (B and C). You could just as easily write it as P (A B ∧ C) but it is notational convention to use a comma. Think of everything after the vertical bar as a list of the given things, separated by commas.

P (A) – the probability that the stock price increases by 5% P (B) – the probability that the CEO is replaced P (A B) – the probability of the stock price increases by 5% given that the CEO has been replaced WebP (A and B) = P (A)P (B A). From this definition, the conditional probability P (B A) is easily obtained by dividing by P (A): Note: This expression is only valid when P (A) is greater … fire flint
