Beta distribution

[Math_] Neat fact about the Beta distribution: starting with a uniform prior, after observing k/n successes, the CDF for parameter p (the probability of success in a single trial), i.e. the probability that p is smaller than a certain value x, is equal to the probability that we get k+1 or more successes out of n+1 trials using that x!
