Basic Probability Let us consider a sequence of Bernoulli trials with a probability of success p. Such a sequence is observed until the first success occurs. We denote by X the random variable (RV), 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)^(r-1) * p This means that there will be x-1 failures before the occurrence of the first success at the x-th trial. The RV X, defined as above, is called the geometric RV with parameter p. Solve the following tasks. Hint: use the sum of the geometric series C(n) = Σ(a^n) = C(0) * (1 - r^n) / (1 - r) for |r| lt; 1. Prove that the geometric RV satisfies the total probability axiom, or in other words, X * Px(x) = 1.
