 Rather than generating `_cachedFailedTrials` by doing many independent queries to a random number generator we can use some math to speed this up. The probability `_cachedFailedTrials` has some particular value `X` is given by the [Geometric distribution](https://en.wikipedia.org/wiki/Geometric_distribution). We can use [Inverse Transform Sampling](https://en.wikipedia.org/wiki/Inverse_transform_sampling) to generate random values for this distribution directly. The CDF for the Geometric distribution is `1-(1-p)^(floor(x)+1)` which means the inverse is `floor(ln(1-y)/ln(1-p))`.
 
-We've been using BigInteger so far because mathmatically there is a non-zero probability of getting an arbitrarily large number of failed trials in a row. In practice however our PRNG has its outputs constrained to return a floating point number with value k/MAX_INT for an integer value of k between 0 and MAX_INT-1. The largest value PopulateTrials() can return under these constraints is ~2.148M which means a 32bit integer can easily accomodate the value. The perfect mathematical model of the Geometric distribution has a 0.00000005% chance of getting a larger run of failed trials but our PRNG rounds that incredibly unlikely case to zero probability.
