Certain congenital disabilities are polygenic in nature. Typically, the chance that a child will be born with a polygenic disability is small. However, once a child is born with a polygenic disability, the probability that future children from the same parents will be born with the same disability increases. Assume that the probability of a child being born with polygenic disability A is 0.001. If a couple has a child with this disability, then the probability that the same couple has another child with the same disability becomes 0.04.

If a couple plans to have two children, determine the probability that both children will be born with the disability.
