Why is it a 50-50 chance that a baby will be a boy/girl rather than something else, like 55-45, etc.?

Actually, there exists a probably of either 0 or 1 that a given baby is a boy (or girl). As one cannot assign an intermediary probability (between 0 and 1) to a single event. You can, however, assign an intermediary probability to a series of events; for example, what is the probability that a baby will be born in a given population. Then you would use a proportion, and if you wanted to test the level of significance do a hypothesis test and so on.
