The probability of a woman exposed to German Measles will contract it is 0.2. If exposed to risk while pregnant the probability is 0.1 that the child will suffer a particular serious birth defect; otherwise the chances of this birth defect are 0.01. A child was born with this birth defect, what is the probability that the mother suffered from German Measles while pregnant?

@Zarkon can you help me with this one too? I thought it might be:
p(german measles given that there is a birth defect) so [p(german measles + birth defect)] divided by the probability of a birth defect but that didn't work
