May 1, 2024 3 minute read

The Law of Large Numbers (LLN) is a fundamental theorem of probability theory that describes the behavior of averages of random variables as the sample size increases. It states that as the sample size approaches infinity, the average of the random variables will converge to the expected value of the random variables.

Understanding the Law of Large Numbers

Imagine you flip a fair coin repeatedly. The probability of getting heads on any given flip is 1/2. According to the LLN, as you continue flipping the coin, the proportion of heads you get will approach 1/2. This is because the average of the random variables (the outcomes of the coin flips) will converge to the expected value (1/2) as the number of flips increases.

Applications of the Law of Large Numbers

The LLN has numerous applications in various fields, including:
