Web35 The Geometric Model (1 of 2) A geometric random variable counts the number of trials until the first success is observed. A geometric random variable is completely specified by one parameter, p, the probability of success, and is denoted Geom(p). Unlike a binomial random variable, the number of trials is not fixed Weba random variable X is geometric provided that the following conditions are met: (a-c are same as binomial) a) each observation falls into one of just two categories, called success or failure b) probability of a success, p, is the same for each observation c) observations are all independent NEW
