What's In
Remember that a variable is a quantity that may change within the context of a
mathematical problem or experiment. Typically, we use a single letter to represent a
variable. The letters x, y, and z are common generic symbols used for variables. In
this lesson, we shall discuss variables that are associated with probabilities, called
random variables.
