It has been observed that the average number of traffic accidents requiring medical assistance on the Killer Highway between 7 and 8 AM on Wednesday mornings is 1. What, then, is the chance that there will be a need for exactly 2 ambulances on the said highway, during that time slot on any given Wednesday morning? The hospital dispatcher needs to know.

Ex. A large number of insects are expected to be attracted to a certain variety of rose plant. A commercial insecticide is advertised as being 99% effective. Suppose 200 insects infest a rose garden where the insecticide has been applied. What is the probability that none of these insects can survive? Random variable: X – number of dead insects Distribution: X-Bin(200,0.99) Computation: P[X = 200] = (200) + 0.99200 * 0.01° = 0.1340
