What Is The Expected Value Of X ?

The graph below defines a probability distribution for x. The expected value of a random variable is a weighted average of the values that zcan take, where the weights are given by the probability of obtaining that value. Quiz questions test your understanding of what the expected value is, identifying variables involved in finding expected value, and applying what you've learned to solve a problem.
