Question

what is true regarding a discrete random variable? it has a countable number of possible outcomes. it has an uncountable number of possible outcomes. it is a type of qualitative data. the outcomes are represented by an interval on the number line. i dont know one attempt

Explanation:

A discrete random variable is defined as a variable that can take on a countable number of distinct values. For example, the number of students in a class (it can be 20, 25, etc., and these values can be counted one - by - one). Qualitative data is non - numerical (like colors: red, blue), and a discrete random variable is numerical. An uncountable number of outcomes is a characteristic of a continuous random variable (e.g., the time it takes for something to happen, which can take any value in an interval). Also, the outcomes of a discrete random variable are distinct points (not an interval on the number line).

Answer:

It has a countable number of possible outcomes.
