The Poisson distribution is used when we want to predict the number of times an event will occur in a specific time interval. In this case, we want to find the probability of ten customer arrivals in one hour at a service station. The Poisson distribution is ideal for this situation, as it models the probability of a certain number of events occurring in a fixed time interval when the events occur independently and at a constant rate.
