Based on what I have seen, however, I wish I had another plot, this time the Poisson distribution as you have presented it, only for lambda = 18 (3 hour expected network block production), and running out to k = 36. 

While I am wishing, I also want a numeric table of the cumulative distribution function for the same distribution.

here you are:

1. probability of exactly n block within 3 hours:



2. cummulative numeric, that is probability to have <= n blocks within 3 hours:
Code:
