In this lesson, we will learn how to identify a discrete random variable and define its corresponding probability distribution.

Students will be able to

understand what a discrete random variable is,
determine whether a random variable is discrete given a context,
identify the sample space of an experiment,
represent the probability distribution of a discrete random variable using a table, probability mass function, or a diagram,
find unknown values given the table or function of a discrete random variable,
determine if a function or table for a discrete random variable is valid or not,
find a probability table or function given a context,
calculate probabilities of events given a probability distribution.
