I need help with these binomial distribution questions. Thank you.

Part 1: Multiple Sclerosis In Individuals with multiple sclerosis (MS), the Immune system attacks the fatty protective myelin sheath that covers the nerve fibers - causing communication problems between the brain and the rest of the body that can result in permanent damage or deterioration. Approximately 15% of people with MS experience a disease subset known as primary-progressive (PPMS), characterized by gradual onset and steady progression of signs and symptoms. Dr. Flynn has 17 patients in her practice diagnosed with MS. The number of these with PPMS Is recorded. Initial Questions 1. Show that this situation can be modeled by a binomial distribution. For credit, you must discuss each of the criteria required for a binomial experiment. (12 pts) 2. Define the random variable X in this scenario, using the words of the problem. (2 pts) 3. List all possible values of X for this situation. (2 pts) 4. On one trial for this scenario, what does "success" mean? Explain using the words of the problem. (4 pts)
