### Question:
TriangularDistribution extends AbstractContinuousDistribution { @Override public double getSupportLowerBound() { return a; } TriangularDistribution(double a,
                                  double c,
                                  double b); double getMode(); @Override double density(double x); @Override double cumulativeProbability(double x); @Override double getMean(); @Override double getVariance(); @Override double getSupportLowerBound(); @Override double getSupportUpperBound(); @Override boolean isSupportConnected(); @Override double inverseCumulativeProbability(double p);  }### Answer:
@Test void testGetLowerBound() { final TriangularDistribution distribution = makeDistribution(); Assertions.assertEquals(-3.0, distribution.getSupportLowerBound()); }
