... The only two-digit cubes are 27 and 64. If 1 across is 64, then 1 down must also be 64 (the only square between 61 and 69 inclusive), but there must be a different digit in each square so this is impossible. Hence 1 across is 27 and 1 down is 25. The possibilities for 2 down are now 71, 73 and 79 gi ...

... From the definition of reliability given earlier (10), we note that the reliability of the combined measure is p2 / (p2 + 0.5*err2). However, from previous expressions we can see that either measure alone has a reliability of p2 / (p2 + err2). It is thus apparent that the combined measure is m ...

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)
