What are the main features of Risk and Uncertainty in relation to financial modeling? 1.Risk and Uncertainty factors require little consideration from the financial modeling perspective, as both cover easily insurable events 2. Risk is about financial modeling, but uncertainty should be handled in product design and engineering 3.Risky events are harder to model than uncertain events, because risky events always have a greater impact on financial modeling than uncertain events 4.Risky events are associated with known probability and impact distributions, while uncertain events require relatively subjective modeling of their potential likelihoods and impacts. Explain.
