Question 534240
If a person were to have 14 children in a row, all female, what is the probability that the next child will be female?
<pre>
Your teacher probably wants you to answer {{{1/2}}}.  This may be the correct
answer in a math class. However, this is not the case in reality. Some men's
sperm contains more X chromosomes that Y-chromosomes, as is likely the case
since he's fathered 14 female children.  So in reality the probability would be
much higher than {{{1/2}}}.
