Probability function

Unfortunately I do not know which statistical functions are available in Numbers '08 (I have '09) nor am I versed on statistics. However, a web search on excel random probabilities will give a bunch of hits.

Here is info from one site:

If we want to generate a random number having distribution Normal(μ,σ2) we can do it by the inverse transformation method. As we will see in class, if F(x) is the CDF of a random variable, F−1(y) is its inverse, and U is a uniform random number in [0, 1], then F−1(U) is a random observation from the distribution F . In Excel we can do this by typing NORMINV(RAND(), μ, σ) where μ is the mean and σ is the standard deviation.

Numbers 09 has NORMINV, Numbers 08 does not.

I just looked at the Number '08 guide. The statistics functions are very limited. Maybe something in this link will help:
