The Law of Large Numbers says that if you take samples of larger and larger size from any population, then the mean of the sample is very likely to get closer and closer to µ. This is discussed in more detail in The Central Limit Theorem.
Note: The formula for the mean is located in the Summary of Formulas section course.
