The document discusses the law of large numbers, which states that as the number of trials or observations increases, the empirical probability or sample average will get closer to the actual or theoretical probability. It provides examples of flipping a coin and money in a wallet. The history of the concept is explored from its foundations with Cardano and Bernoulli to its naming by Poisson. Applications discussed include roulette odds stabilizing with more spins, Tesla's growth rates changing as it scales up, and its use in insurance risk calculation.
