Letter C?? 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: P(X = ?) 0.18 0.276 0.228 0.193 0.068 0.038 0.013 0.003 0.001 a.
