De Moivre is notable in the history of actuarial thought for the publication of two books that span the related fields of probability and life contingencies: Doctrine of Chances,31 which was first published in 1718; and Annuities on Lives,32 first published in 1724. The latter is the main focus of our interest, but Doctrine of Chances is remarkable for including the first published derivation of the normal probability distribution. De Moivre considered Jacob Bernoulli’s binomial probability distribution and, like Bernoulli, he considered the properties of samples from the distribution as the sample size increased to very large numbers.

E. the posterior median; and the value that minimises the probability-­weighted sum of the absolute differences between the observed value and the best estimate, where the probability weights were obtained from the posterior distribution. Laplace then proved that these two approaches were mathematically identical and hence would always produce the same value for the best estimate. Laplace also moved beyond Bayes in terms of to what he applied the Bayesian prior/posterior framework. Bayes’ paper had focused on binary events (success or failure; a ball landing to the right or left of another).

But this doesn’t really address the original point of the paradox, which was that, if the game was offered, no reasonable person would intuitively be prepared to pay more than ten or twenty times the pay-off from the first coin toss, even though the total expected pay-off is infinite.
