When considering the symmetrix approximation and Monte Carlo risk approaches, the correct answer is.
a. both are constrained to treating the cost elements as being dependent
b. the symetric approximation generally assumes the cost elements are independente, while the Monte Carlo can address dependencies.
c. Both are constrained to treating the cost elements as being independent
d. The symmetric approximation treats the cost elements as if they were dependent, while the Monte Carlo generally assumes independence.
