Find the pmf of x

WebLet X be a Poisson random variable. Then, the PMF of X is p X(k) = λk k! e−λ, k = 1,2,..., where λ>0 is the Poisson rate. We write X ∼Poisson(λ) to say that X is drawn from a Poisson distribution with a parameter λ. Understanding the parameter: X = number of arrivals α= arrival rate = number per unit time t = time WebProblem 1.9.2. Let p(x) = 1=2x, x= 1;2;3;:::, zero elsewhere, be the pmf of the random variable X. Find the mgf, the mean, and the variance of X. Solution 1.9.2.

WebWe found the joint pmf for \(X\) and \(Y\) in Table 1 of Section 5.1, and the marginal pmf's are given in Table 2. We now find the conditional distributions of \(X\) and \(Y\). First, to find the conditional distribution of \(X\) given a value of \(Y\), we can think of fixing a row in Table 1 and dividing the values of the joint pmf in that row ...
