Question 568919: A man claimed not to be the father of a certain child. On the basis of evidence presented, the court felt that this man was twice as likely to be the father as not. The blood type of the child is solely determined by the father, if it did not match the blood type of the child, than he could not be the father. The blood type of the child only occurred in only 10% of the population. The blood test indicated that the man had the same blood type as the child, what is the probability that the man is the father?
Thank You!
