Extracted text: Premature aging gene. Ataxia-telangiectasia (A-T) is a neurological disorder that weakens immune systems and causes premature aging. Science News reports that when both members of a couple carry the A-T gene, their chil- dren have a 1 in 5 chance of developing the disease. 1. a. Consider 15 couples in which both members of each couple carry the A-T gene. What is the probability that more than 8 of 15 couples have children that develop the neurological disorder? b. Consider 10,000 couples in which both members of each couple carry the A-T gene. Is it likely that fewer than 3,000 will have children that develop the disease?
