random numbers
... The common generators are cyclic in nature. There is an L -- large integer such that ri + L = ri , hence the number of random numbers that can be generated is finite. Widely used random number generators are based on the following simple (and fast) operations: I k +1 = α I k + β (mod m) The integers ...

Thus, the distriubtion of lists should correspond to the distribution of possible outcomes of the random variable. Of course, ...

... |N − n/2| > a n is at most e−a /2 . The chance of seeing at least 625 heads in 1000 tosses of an unbiased coin is less than 5.3 × 10−7 . These are pretty strong bounds! Of course, for finite n the sum of n random variables need not be an exact Gaussian and that’s where Chernoff bounds come in. (By t ...

Law of large numbers
In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.The LLN is important because it ""guarantees"" stable long-term results for the averages of some random events. For example, while a casino may lose money in a single spin of the roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. It is important to remember that the LLN only applies (as the name indicates) when a large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be ""balanced"" by the others (see the gambler's fallacy)
