After combinatorics, SpeedCrunch has just been enhanced with its first probability support. This was indeed my favourite mathematics subject when I was a student, so I decided to implement some discrete distributions. So for now we've got three available: Binomial, Hypergeometric and Poisson.
Available for each distribution are functions for probability mass, cumulative distribution, mean and variance. If you usually need some others or find them useful even if you don't use them, please tell us.
I've got many more further plans on these topics for the next SpeedCrunch releases, but I'll leave it like this for 0.8. There are still some open higher priority issues and not much time left to 0.8alpha, so let's focus on bug fixing.
