What is the random​ variable, what are its possible​ values, and are its values​ numerical the random variable is​ x, which is the number of girls in three. A random variable is a function x that assigns a numerical value to each outcome in a sample space random variables that have only finitely many values are. If a random variable can take on only specific exact numerical values, it is called on any numerical value within some interval, it is called a continuous random.
