The number of different mathematics courses at community colleges has a Poisson Distribution with a mean of 20 courses per college.


*show your basic keystrokes and round your answer to 4 decimal places.



  1. What is the probability there will be fewer than 38 courses at 2 colleges?


Someone on this site already answered this question, but I don't understand what they did, how they got the number 40 for this problem to solve it. Can you help me understand this please? I also didn't know if this was poissoncdf or poissonpdf.
