... the outcomes of the game. Save your chart as you will use this random record several times later in the course to test and illustrate some of the theorems. Each “gambler” flips the coin, and records a +1 (gains $1) if the coin comes up “Heads” and records −1 (loses $1) if the coin comes up “Tails”. ...

... The other properties of a probability measure can be checked in a similar manner. In the case that the r.v. X is real-valued, we say that that the induced measure is the distribution of X, and describe this measure by its cumulative distribution function (cdf), FX (s) = P(X ≤ s). Theorem 6.1.1 A cdf ...

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)
