If the first child of the parents in problem 5 is feeble-minded, what is the probability that the second child will be feeble-minded? (This is akin to asking the question, if on a throw of the die, I threw a six, what is the probability that I will throw a 6 the second time? Note that this is a different question that what is the probability of throwing two 6's with two throws of the die.)
