Confusion of the Inverse Using the same events F and H described in Exercise 3, describe confusion of the inverse. At Least One. In Exercises 5-12, find the probability. 5. Three Girls Find the probability that when a couple has three children, at least one of them is a girl. (Assume that boys and girls are equally likely) 6. Probability of a Girl Assuming that boys and girls are equally likely, find the probability of a couple having a boy when their third child is born, given that the first two children were both girls. 7. Births in the United States In the United States, the true probability of a baby being a boy is 0.512 (based on the data available at this writing).

Explanation / Answer

Probability of birth of baby girl is 1/2 = 0.5

Also, the events of birth of childs are independent. There is no impact of gender of the first two child of a couple on the gender of the third child.

Hence required probability is 1/2 = 0.5
