Data were collected from a survey given to graduating college seniors on the number of times they had changed majors. From that data, a probability distribution was constructed. The random variable X is defined as the number of times a graduating senior changed majors. It is shown below: x 0 1 2 3 4 5 6 7 8 P(X = x) 0.26 0.249 0.157 0.199 0.078 0.032 0.02 0.003 0.002 a.
