Answer 3

"Discrete random variable" means, basically, something that can be "counted" in whole numbers. Measurements, like temperature, height, elapsed time, etc, can't be "counted" and are measured on continuous scales (limited only by the precision of the measuring instrument), so they are not "discrete".
