Hey pinholers, a probability question:
Let's pretend that you meet a person and she says that she has only
one sibling. What is the probability that her sibling is a boy? How
about a girl? I'm pretty sure that it is not 50:50....
(So, in real life, if you meet a woman with one sibling, is there
really a better chance of her having a brother than a sister?)
