The geometric distribution is a probability distribution of the number X of Bernoulli trials needed to get one success. For example, how many attempts does a basketball player need to get a goal. Given the probability of success in a single trial is p, the probability that the xth trial is the first success is: Pr(x = x|p) = (1 - p*-'p for x=1,2,3,.... Suppose, you observe n basketball players trying to score and record the number of attempts required...

Basic Probability Let us consider a sequence of Bernoulli trials with probability of success p. Such a sequence is observed until the first success occurs. We denote by X the random variable (r.v.), which gives the trial number on which the first success occurs. This way, the probability mass function (pmf) is given by Px(x) = (1 – p)?-?p which means that will be x 1 failures before the occurrence of the first success at the x-th trial. The r.v....

We have seen that the geometric distribution Geo(p) is used to model a random variable, X that records the trial number at which the first success isachieved after consecutive failures in each of the preceding trials ("success" and failure being used in a very loose sense here). Here, p is the success probability in each trial. We described the geometric distribution using the probability mass function: f(X)(1- p)*-1p, which computes the probability of achieving success in the xth trial after...

A discrete probability distribution differs from a continuous probability distribution, by only taking values on a discrete set (like the whole numbers) instead of a continuous set. The geometric distribution is a discrete probability distribution which measures the number of times an experiment must be repeated before a success occurs. For example, in this problem, we will roll a fair six-sided die until the number six occurs, at which point we stop rolling. (a) If we are rolling a die,...

If a procedure meets all of the conditions of a binomial distribution except the number of trials is not fixed, then the geometric distribution can be used. The probability of getting the first success on the xth trial is given by P(x)=p(1-p)x-1, where p is the probability of success on any one trial. Subjects are randomly selected for a health survey. The probability that someone is a universal donor (with group O and type Rh negative blood) is 0.07. Find...
