Son vs daughter riddle

Are you confident enough with your answer?
  1. In a two-child family, one child is a boy. What is the probability that the other child is a girl?
  2. In a two-child family, the elder child is a boy. What is the probability that the other child is a girl?
Special: All the best to the S&R Team for MH370, we're counting on you!

  2. Actually, the answer to the first is 100%. One child is a boy!
    You (confidently) got the second one right though, well done!
