Complete the following table to compute the answers below it. Enrollment (X) P(X) 2 kids 0.1 4 kids 0.3 6 kids 8 kids 0.4 ТОTAL a. What is the likelihood of a class enrolling 8 children? b. Find the average number of students we would expect to be enrolled in a given class. c. Find the associated standard deviation.
