As the Mean increases
So as λ increases the Poisson distribution fits the Normal distribution.

Poisson Graphs from the spreadsheet from the lab were selected for simplicity: 4,6,7,8,9,10
Poisson Probability
There is a probability for the frequency of those events to occur. This is know as the Poisson Probability. Here are 3 examples. This is also on the Poisson Worksheet.
