| Abstract: | The article focuses on the historical development of modern probability theory through the "problem of points," a puzzle about fairly dividing stakes in an interrupted game of chance. Early attempts by Luca Pacioli and Niccolò Tartaglia to solve the problem were flawed, as they did not account for future possibilities in the game. In the 17th century, Blaise Pascal and Pierre de Fermat corresponded to provide the first rigorous solutions by calculating expected values based on all possible future outcomes, laying the foundation for probability theory. Their methods underpin contemporary risk assessment practices used in fields such as insurance, finance, and gambling by quantifying uncertain outcomes through weighted averages of possible scenarios.
