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....
