Not enumerating all positive rational numbers
... Therefore for any n0 ¥ 6 we can take k = n0/2. Then the interval (n0/2, n0] Õ sn0. This means, there are arbitrarily large sequences of undefiled unit intervals (containing no rational number with an index n or less) in the sets sn. It is easy to find a completely undefiled interval of any length or ...

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)
