The questions below can presumably be answered in terms of ProbabilityDistribution, so here goes... How do I create a distribution for the discrete random variable whose support is {-2.1, 3.45, 7} having corresponding probabilities {0.5, 0.3, 0.2}? What if the support is {-2.1, 3.45, pi}? If ProbabilityDistribution cannot support these, then what? Thanks. Bruce
