[#118] In ___________ models there is risk and uncertainty.
Correct Answer
(B) Probabilistic Models

Solution: In Probabilistic Models there is risk and uncertainty. Probabailistic models incorporate random variables and probability distributions into the model of an event or phenomenon. While a deterministic model gives a single possible outcome for an event, a probabilistic model gives a probability distribution as a solution.
[#119] ___________ models are obtained by enlarging or reducing the size of the item.
Correct Answer
(A) Iconic Models
Explanation
Solution: Iconic models represent the system as it is, but in different size. Thus Iconic models are obtained by enlarging or reducing the size of the system. In other words they are images Some common examples are photographs, drawing model airplanes, ships, engines, globes, maps etc. A toy airplane is an iconic model of a real one.
[#120] Operations Research attempts to find the best and __________ solution to a problem.
Correct Answer
