Final answer:
Yes, random variables are used in engineering to model uncertainties and variability in different processes and systems.
Step-by-step explanation:
Yes, random variables are used in engineering. In engineering, random variables are often used to model uncertainties and variability in different processes and systems. For example, in reliability engineering, continuous random variables can be used to model the length of time a component or system lasts. Similarly, in quality engineering, discrete random variables can be used to model the number of defects in a product or the number of accidents in a workplace.
