Guillain-Barré syndrome (GBS) is an autoimmune disorder affecting the peripheral nervous system.  In a study of the relationship between measles vaccination and Guillain-Barré syndrome, Silveira et al used a Poisson model in the examination of the occurrence of GBS during latent periods after vaccinations.  They conducted their study in Argentina, Brazil, Chile, and Colombia.  They found that during the latent period, the rate of GBS was 1.28 cases per day.  (Ref: The Lancet 1997; 349:14-16.)  Using this estimate, find the probability on a given day of:   No cases of GBS  More than two cases of GBS.
