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: T 0 1 2 3 4 5 0.26 0.33 0.29 0.08 0.03 0.01 Give answers to at least 4 decimal places, if necessary. a. What is the probability that a randomly selected student changed his or her major at least once? b. What is the probability that a randomly selected student changed his or her major at most twice? c. Given that a randomly selected person did change majors, what is the probability that he or she changed majors more than three times? Submit
