    The boy/girl odds for a single child are 51/49–males are slightly more likely than girls.  Oddly, after having a boy, the odds are 50/50 for the second child to be a boy, even though the odds for a third boy after the first two are boys jumps up to 52.3%.

    So the correct answer is also the intuitive answer: 50%
