... Theorem. Given a Mersenne number m = 2n − 1 (with n a nonnegative integer), the Collatz sequence starting with m reaches 3n − 1 in precisely 2n steps. Also, the parity of such a sequence consistenly alternates parity until 3n − 1 is reached. For example, given 22 − 1 = 3 gives the Collatz sequence 3 ...

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)
