Inverse exponential Distribution formulas

X : a random variable following a exponential distribution of parameter `lambda > 0`.

The inverse of the cumulative distribution function F(x) is also called the 'quantile function', denoted Q(x). We have,

`F(x) = 1-exp(-lambda*x)`   for `x >= 0`

which inverse function is,

`Q(x) = -(ln(1-x))/lambda`
