WebNow, x 1 follows a geometric distribution with p = 5/6, and so as we observed following Figure 3 of Negative-Binomial and Geometric Distributions, the expected value of x 1 is 1/p = 6/5. Similarly, x 2 follows a geometric distribution with p = 4/6, and so the expected value of x 2 is 1/p = 6/4. The binomial distribution describes the probability of obtaining k successes in n binomial experiments. If a random variable X follows a binomial distribution, then the probability that X = ksuccesses can be found by the following formula: P(X=k) = nCk * pk * (1-p)n-k where: 1. n:number of trials 2. k: number of … See more The geometric distributiondescribes the probability of experiencing a certain amount of failures before experiencing the first success in a … See more In each of the following practice problems, determine whether the random variable follows a binomial distribution or geometric distribution.
