Let \(p(y)\) denote the probability function associated with a Poisson random variable with mean \(\lambda\) a. Show that the ratio of successive probabilities satisfies \(\frac{p(y)}{p(y-1)}=\frac{\lambda}{y}\), for \(y=1\), 2,.... b. For which values of is \(p(y)>p(y-1)\)? c. Notice that the resul
