The probability that A and B occur together is . P(A and B) = P(A) x P(B) P(A and B and C)= P(A) x P(B) x P(C) Example 1: Consecutive Floods. Find the probability that a 100-year flood (a flood with a 0.01 probability of striking in a given year) will strike a city in two consecutive years.

Defn: Conditional probability is the probability of one event, A, GIVEN that another event, B, has already occurred and is denoted by Pr { A | B } = probability of A given B. Notes. 1. Pr { A } is actually a conditional probability, namely, Pr { A | S }, but is never written as such! 2.

Conditional probability - Wikipedia
Notation: P(A|B) is read “the probability of A given B” and is the conditional probability of event A occurring given that event B has occurred. This concept allows us to implement additional knowledge into our models. DEFN: The . union. of events A and B is the set of all elements that occur in either A . OR. B …
