Lesson: Expected Values of Discrete Random Variables Mathematics
In this lesson, we will learn how to calculate the expected value of a discrete random variable from a table, a graph, and a word problem.
The table shows the probability distribution of a fair six-sided die. Determine .
An experiment produces the discrete random variable that has the probability distribution shown. If a very high number of trials were carried out, what would be the likely mean of all the outcomes?
Work out the expected value of the random variable whose probability distribution is shown.
