Quiz 7.1C. Quiz 7.1C. Suppose that 60% of all the issued bonds were A rated, and 10% of all the issued bonds were rated C. Of the municipal bonds rated A, 50% were issued ; Suppose that you live in a community that has 125,000 households. B. Given that you are going to "select" exactly two children, find the probability that they are BOTH girls (it's a coin flip, so p = 50% = 0.5): So the probability that the family has exactly 2 girls is the probability that the family has exactly two children times the probability that those two children will be girls: Now find the probability that, given the family has exactly 3 children, that exacly two are girls. What fraction of the families with at least two girls is this? Conditional Probability : what is the prob.
