WebThe Poisson distribution is used to model the number of events that occur in a Poisson process. Let X \sim P (\lambda) X ∼ P (λ), this is, a random variable with Poisson … WebIf we already know the PMF of X, to find the PMF of Y = g ( X), we can write P Y ( y) = P ( Y = y) = P ( g ( X) = y) = ∑ x: g ( x) = y P X ( x) Let's look at an example. Example Let X be a discrete random variable with P X ( k) = 1 5 for k = − 1, 0, 1, 2, 3. Let Y = 2 X . Find the range and PMF of Y. Solution
