If a procedure meets all the conditions of a binomial distributionexcept that the number of trials is not fixed, then the geometric distribution can be used. theprobability of getting the first success on the xth trial is given by p(x)=p(1−p)x−1, wherep is the probability of success on any one trial. subjects are randomly selected for the nationalhealth and nutrition examination survey conducted by the national center for healthstatistics, centers for disease control and prevention. the probability that someone is a universaldonor (with group o and type rh negative blood) is 0.06. find the probabili ty that thefirst subject to be a universal blood donor is the fifth person selected.
