A 22-year-old woman presents to her primary care physician for a yearly check-up. She has no past medical history and recently finished getting a college degree in computer science. Her body mass index is 21.2 kg/m^2 and she has no medical concerns. Her primary care physician decides to get a panel of metabolic tests and the results show a fasting glucose of 231 mg/dL. Immunologic testing reveals no autoantibody production nor any beta-cell targeting T-cells. If this patient has 2 children in the future, and her husband is not affected by this disorder, which of the following best represents the probability that at least 1 child will develop this disease?
