public class CoinTossLawOfLargeNumbersExperiment
extends Experiment
implements java.io.Serializable

This experiment consists of tossing n coins, each with probability of heads p. The Proportion of Heads (P) and the differences of Heads and Tails (D) are recorded on each update. The discrete probability density function is shown in blue in the distribution graph and are recorded in the distribution table. On each update, the empirical probability density function and moments of the selected variable are shown in red in the distribution graph and are recorded in the distribution table. The parameters n and p can be varied with scroll bars.
