Question

a. it is a continuous random variable.
b. it is a discrete random variable.
c. it is not a random variable.

Explanation:

The amount of rain can take on any non - negative value within a certain range (e.g., 0.5 inches, 1.23 inches). A continuous random variable can assume an uncountable number of values within a given interval. A discrete random variable has a countable number of distinct values. Since the amount of rain is not restricted to only whole numbers or a countable set of values, it is a continuous random variable.

Answer:

A. It is a continuous random variable.
