FYI: In 1733 Abraham de Moivre, drawing on the work of Jacob and Nicolaus Bernoulli, calculus, and the underlying structure of Pascal's Triangle, demonstrated how a set of random drawings would distribute themselves around their average value. De Moivre's distribution is know today as a normal curve. It makes it possible to evaluate the probability that a given number of observations will fall within some specified bound around a true ratio.
