They are called the strong law of large numbers and the weak law of large numbers. [ 16 ] [ 1 ] Stated for the case where X 1 , X 2 , ... is an infinite sequence of independent and identically distributed (i.i.d.) Lebesgue integrable random variables with expected value E( X 1 ) = E( X 2 ) = ... = μ , both versions of the law state that the ...
The law of truly large numbers (a statistical adage), attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible (i.e. unlikely in any single sample, but with constant probability strictly greater than 0 in any sample) result is likely to be observed.

Littlewood’s law of miracles states that in the course of any normal person’s life, miracles happen at a rate of roughly one per month. The proof of the law is simple. During the time that we are awake and actively engaged in living our lives, roughly for 8 hours each day, we see and hear things happening at a rate of about one per second.
Law of large numbers; Law of truly large numbers; Central limit theorem; Regression toward the mean; Examples of "laws" with a weaker foundation include: Safety in numbers; Benford's law; Examples of "laws" which are more general observations than having a theoretical background: Rank–size distribution
An example is the weak law of large numbers. The law states that for a sequence of independent and identically distributed (IID) random variables X 1, X 2, ..., if one value is drawn from each random variable and the average of the first n values is computed as X n, then the X n converge in probability to the population mean E[X i] as n → ∞ ...

Objectivists assign numbers to describe some objective or physical state of affairs. The most popular version of objective probability is frequentist probability , which claims that the probability of a random event denotes the relative frequency of occurrence of an experiment's outcome when the experiment is repeated indefinitely.
