Description
This lesson, which is divided into two parts, develops the concept of the expected value of a discrete random variable as the mean of the distribution of the discrete random variable. In Exploratory Challenge 1, the method for computing the expected value of a discrete random variable is developed. In Exploratory Challenge 2, this lesson relates the method for computing the expected value of a discrete random variable to previous work with vectors (i.e., the computation of the dot product of two vectors).
