ta were collected from a survey given to graduating college seniors on the number of times they had anged majors. From that data, a probability distribution was constructed. The random variable X is ined as the number of times a graduating senior changed majors. It is shown below: 0. 1 4. P(X = 1) | 0.234 0.264 0.203 0.172 0.071 0.032 0.019 0.003 0.002 8 1. What is the probability that a randomly selected student changed his or her major at least once? What is the probability that a randomly selected student changed his or her major at most twice? Given that a randomly selected person did change majors, what is the probability that he or she changed majors more than three times? Round your answer to three decimal places.)
