Example

Determine the probability profile of adding 3 six-sided dice together

// Create a profile for a 6-sided dice

Fraction prob = new Fraction(1, 6);

Map<Integer, Fraction> map = new TreeMap<Integer, Fraction>();

for (int n = 1; n <= 6; n++) {
	map.put(n, prob);
}

ComparableEventProbabilityProfileImpl<Integer, Fraction> dice 
	= new ComparableEventProbabilityProfileImpl<Integer, Fraction>(
		map, new FractionOperator());

// Determine the probabilities of all possible results of adding the dice values together 
// using the EventProbabilityProfileAdditionAggregationStrategy

EventProbabilityProfileAggregator<Integer, Integer, Fraction> aggregator 
	= new EventProbabilityProfileAggregator<Integer, Integer, Fraction>(
		new EventProbabilityProfileAdditionAggregationStrategy<Integer>(
			new IntegerOperator()), new FractionOperator(), dice, dice, dice);

// Print out the results to the console

System.out.println(aggregator);
