Correct answer: Jacob Bernoulli.

The law of large numbers is a law that describes the probability properties of multiple experiments. However, it should be noted that the law of large numbers is not an empirical law, but a theorem that has been strictly proved under some additional conditions. It is a natural law, so it is usually not called a theorem, but a "law" of large numbers. The theorem of large numbers we talk about is usually proved by mathematicians and named after them, such as Bernoulli's theorem of large numbers.
