Chapter 3 . The joint probability density function has the following properties: f (x, y) > 0 for all x and y f (x, y) dy dx 1 Summary Variables a … Probability of an Event Occuring P(E) = n(E) s(E) n(E) = number of elements in event E s (E) = total elements in sample space s Odds in favor of an event given Probability Given probability of an event occurring equal to a b Odds = a to b a Probability of event occurring given odds Given odds of event E occurring equal to a to b P(E) = a a+b All outcomes are equally likely.

Engineering Formulas Mode Mean n = number of data values max events A and B and C occurring in sequence x A q = 1 P(~A) = probability of event A Engineering Formula Sheet Probability Conditional Probability Binomial Probability (order doesn’t matter) P k (= binomial probability of k successes in n trials p = probability of a success If the experiment can be repeated potentially inﬁnitely many times, then the probability of an event can be deﬁned through relative frequencies. In the following sections, we are going to keep the same notations as before and the formulas will be explicitly detailed for the discrete (D) and continuous (C) cases. ˇ ˇˆ ? Formula Sheet .
