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 \( \mathrm{X} \) is defined as the number of times a graduating senior changed majors. It is shown below: a. What is the probability that a randomly selected student changed his or her major at least once? b. What is the probabilitv 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?
