A travel agency wants to describe the number of calls it receives in 10 minutes. The average number of calls in 10 minutes is about 35.
Again, you begin by identifying and entering the values to set the parameters of the Poisson distribution in Crystal Ball. In this example, the conditions show one important value: 35 calls or a rate of 35. The result would be a distribution showing the probability of receiving x number of calls in 10 minutes.
