An experiment consists of determining the speed of automobiles on a highway by the use of radar equipment. the random variable in this experiment is a a. discrete random variable. b. categorical random variable. c. complex random variable. d. continuous random variable.

The random variable in this experiment is a Continuous random variable.

Option D

Explanation:

The continuous random variable is random variable where the data can take infinite variables. For example random variable is taken for measuring "speed of automobiles" on the highways. The radar instrument depicts time taken by automobile in particular what speed. They are the generalization of discrete random variables not the real numbers as a random data is created. It gives infinite sets of all possible outcomes. It is obvious that outcomes of the instrument depend on some "physical variables" those are not predictable as depends on the situation.
