3. Let X be a discrete random variable with PMF \begin{equation} p_X(x) = P(X = x) = \frac{c}{x(x+1)(x+2)}, \quad x = 1, 2, ... \end{equation} 1 (a) Find the normalizing constant $c$ so that $p_x(x)$ is a valid PMF using the identities \begin{align*} \frac{1}{n(n+1)(n+2)} &= \frac{1}{n(n+1)} - \frac{1}{n(n+2)} \\ \frac{1}{n(n+1)} &= \frac{1}{n} - \frac{1}{n+1} \\ \frac{1}{n(n+2)} &= \frac{1}{2} \left(\frac{1}{n} - \frac{1}{n+2}\right) \end{align*} (Answer: $c = 4$.) (b) Show that $E(X) = 2$. (c) Show that $E(X^2) = \infty$. (Hint: $E(X^2) = E[X(X+1)] - E(X)$.)
