General research on the mortality and the propagation of the human race
Euler deals with questions of mortality and life expectancy. In particular, he addresses six questions: (1) A certain number of men, of whom all are the same age, being given, to find how many of them are probably yet alive after a certain number of years; (2) To find the probability that a man of a certain age be still alive after a certain number of years; (3) One demands that probability that a man of a certain age will die in the course of a given year; (4) To find the term in which a man of a given age is able to hope to survive, of the kind that it is equally probable that he die before this term as after; (5) To determine the life annuity that it is just to pay to a man of any age all the years, until his death, for a sum which will have been advanced first; (6) When the interested parties are some infants newly born and when the payment of the life annuities must begin only when they will have attained a certain age, to determine the amount of these life annuities. (These questions are taken from the translation by Richard Pulskamp.)
