Empirical random variable
a list or rtable of samples
(optional) an equation of the form probabilities = plist
The empirical random variable is a discrete probability distribution with probability function generated from the given sample.
If opts is not given, then Maple assigns a probability to each variate present within the sample equal to the fraction of occurrences of that value within the entire sample. If opts is specified, then plist should be a list or rtable of probabilities (nonnegative real numbers adding up to 1), having equally many entries as sample; the ith entry of plist specifies the probability for the ith entry of sample.
Specify the probabilities.
