BETA Probability :

The Beta distribution with parameters α and β is denoted by Be(α,β).
The distribution function of the Be(α, β) distribution is denoted by Be(x | α, β).
For example, Be(.5 | 1,1)=.5.
The density of the Be(α,β) distribution is

f(x) = B(α,β)^-1 x^α-1(1-x)^β-1 on the interval (0,1).

Here B(α,β) represents the beta function, G(α)G(β)/G(α+β),
where G(x) is the gamma function. The Be(1,1) distribution is the uniform distribution, U(0,1).
The distribution of the kth order statistic of a sample of size n from the U(0,1) distribution is Be(k,n+1-k).
