Which of the following characteristics implies that a quantitative model is probabilistic in nature? (a)The fact that it uses random variables.
(b)The fact that it uses an exponential function.
(c)The fact that it measures time in discrete steps.
(d)The fact that it is based on theory rather than data.

(a)The fact that it uses random variables

Explanation:

Quantitative models can be regarded as a compact representations in which

single differential or difference equation may be used in describing performance of the system as regards large set of input functions as well as initial states.Quantitative data can be measured and also can be expressed using numbers and can also be counted. Quantitative methods is based on objective measurements as well as statistical and mathematical, it could be base on numerical analysis of data which is been collected through polls or surveys. It should be noted that one of the characteristics that implies that a quantitative model is probabilistic in nature is the fact that it uses random variables
