If a family has four daughters. What is the probability that a fifth child will be a girl? Does the fact that there are already four daughters in the family increase the probability of having another? Explain please.

I believe that with gender, it's always a 50 - 50 chance. There's no "recessive" or "dominant" gene for gender. So, I'm pretty sure it's always a 50-50 chance. A child is always a special gift though, no matter what the gender.

Nope - the chances of having a girl or a boy hold the same for every pregnancy and are not affected by the sex of previous births.
Basically, the answer is probably 50/50, though because women make up appx. 52% of the American population, the true probability may be slightly more than 50%.

.5. Having other kids doesn't affect the probability at all -- it's like saying that, after getting four tails on flipping a coin, you're more likely to get heads. If you try this out a bit, you'll quickly realize it isn't true. (That is, the previous results are not a determining factor in future results.)
