A random variable can be either discrete or continuous. Discrete Random Variables. Discrete random variables take on a countable number of distinct values.
A random variable is a variable whose value is unknown, or a function that assigns values to each of an experiment's outcomes.

A random variable is called discrete if its possible values form a finite or countable set. A random variable is called continuous if its possible values ...
It is often the case that a number is naturally associated to the outcome of a random experiment: the number of boys in a three-child family, the number of defective light bulbs in a case of 100 bulbs, the length of time until the next customer arrives at the drive-through window at a bank. Such a number varies from trial to trial of the corresponding experiment, and does so in a way that cannot be predicted with certainty; hence, it is called a random variable. In this chapter and the next we study such variables.

For a discrete random variable X the probability that X assumes one of its possible values on a single trial of the experiment makes good sense. This is not the case for a continuous random variable. …

Problem. Let X be a discrete random variable with the following PMF PX(x)={0.1for x=0.20.2for x=0.40.2for x=0.50.3for x=0.80.2for x=10otherwise.
Examples with solutions

A discrete random variable X has a countable number of possible values. Example: Let X represent the sum of two dice. Then the ...
Discrete and Continuous Random Variables:

If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of ...
The probability distribution of a discrete random variable is a list of probabilities associated with each of its possible values. It is also sometimes called the probability function or the probability mass function.
