Ataxia-telangiectasia (A-T) is a neurological
disorder that weakens immune system and causes premature aging.
According to Science News (June 24, 1995), when both
members of a couple carry the A-T gene, their children have a one
in five chance of developing the disease.
- Consider 15 couples in which both members of a couple carry the
A-T gene. What is the probability that more than 4 of 15 couples
have children that develop the neurological disorder?
- Consider 10,000 couples in which both members of a couple carry
the A-T gene. Is it likely that fewer than 3,000 will have children
that develop the neurological disorder?
