A genetic disease occurs in about 1 of every 3000 non dash Caucasian births and about 1 of every 220 comma 000 Caucasian births. If a gene of this disease is denoted with a c and a​ disease-free gene is denoted with a C​ (since the disorder is​ recessive), then only a cc person will actually have the disease. Such persons would ordinarily die before parenting​ children, but a child can also inherit the disease from two Cc parents​ (who themselves are​ healthy, that​ is, have no symptoms but are​ “carriers” of the​ disease). Find the empirical probability that the disease will occur in a randomly selected infant birth among Caucasian s.
