... to the sum of the probabilities of each individual event Question: If 2 coins are tossed, what is the chance that the toss will yield 2 unmatched coins (1 head & 1 tail)? Answer: 1/2 (1 chance in 2) because the combination of 2 unmatched coins can come about in 2 ways: Result A (coin #1 heads, coin ...

A relation between partitions and the number of divisors
... contributions together sum up to d(m). 2. If we decompose the product (1 − X i+1 ) . . . (1 − X n ), this results into terms (−1)l X k1 +...+kl for all sequences of numbers i + 1 ≤ k1 < . . . < kl ≤ n. So this product contributes +1 to αm for each even partition of m with terms greater than i, and i ...

Solving the cubic
... 11. The cubes DC and DF are also equal to the given number. 12. Therefore the cube AE is equal to the given first power and number, which was to be proved. 13. It remains to be shown that 3AC(AB x BC) is equal to the six bodies. 14. This is clear enough if I prove that AB(BC x AC) equals the two bod ...

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)
