public class UrnExperiment
extends Experiment
implements java.io.Serializable

This class defines a basic experiment based on drawing balls from an urn. The balls are red and green. The method sampling (with or without replacement) can be specified, along with the population size, sample size, and number of red balls. The random variable of interest is the number of red balls in the sample.
