Well, unless they are monozygotic twins, then the sex of the second is determined by the sex of the first and the probability of the second being a girl is, for all practical purposes, 100% Smiley
True, but we were to perform the math based entirely on the information at hand.  The odds of identical twins, one kid being horribly mutated so as to fit as a "both" or a "neither", etc etc. are so incredibly small it's unlikely to affect a percentage when displayed as ("###"), which is how we've been displaying it.
