Homework: Probability Distribution FunctionsScore: 8/138/13 answeredPrQuestion 9Data were collected from a survey given to graduating college seniors on the number of times they hadchanged majors. From that data, a probability distribution was constructed. The random variable X isdefined as the number of times a graduating senior changed majors. It is shown below:12.4P(X = 1) | 0.234 0.264 0.203 0.172 0.071 0.032 0.019 0.003 0.0027.8a. 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 shechanged majors more than three times?(Round your answer to three decimal places.)
