The probability that a woman exposed to German measles will contract the disease is 0.2. if exposed to risk while pregnant, the probability is 0.1 that the child will suffer from a particular serious birth defect. Otherwise, the probability of such a defect is only 0.01. A child was born with this birth defect. What is the probability that the mother suffered from German measles while pregnant?

Best ResponseYou've already chosen the best response.0The key point is that the probability of a defect is 0.1 if the mother is exposed, but not infected. If the mother is exposed her chance of getting infected is 0.2.

Best ResponseYou've already chosen the best response.0I still dont get what to do... It sounds like "the child has the birth defect, thus the mother must have had the disease and therefore the probability is 1"
