Can The Law Of Probability Allow A Woman To Give Birth To 9 Consecutive Girls (Without Boys)?
Ah, the law of probability the best law for making money at roulette!
But, the law of probability does, and doesn't affect the outcome of gender in a child. It depends though. Mathematically it is a sound idea that it is possible due to probable odds.
What really decides if you will have 9 consecutive girls is your D.N.A., as well as your spouses D.N.A., and how fertile the female is. I think that females are more common than males for the most part. But, having 9 girls in a row can happen. Just like having 2 sets of twins, it can happen.
Male contribution determines the sex of the infant via an X or Y chromosome, while the female can contribute only an X; so whatever probability lies with the male contribution is to blame or praise.
Probabilities aside, one great aunt of mine had 9 children, each a year apart, and died of hemorrhage after dinner one evening. She'd never healed completely, internally.
There is a 50% chance of each gender under normal circumstances, so the probability of having nine girls in a row is (0.5)^9, or 0.00195. A woman giving birth to nine children will have about a 0.2% chance of having all girls.
It depends on the place. Like in some places, the birth rate of girls are higher, and some places birthrate of boys are higher.
And it also depends on the number also. If you mean that, a woman will give birth to 9 child and everyone will be a girl that means 100% birth rate of the girls-its not possible.
If you mean a woman will give birth to 18 child and 9 will be girls, that means 50% birth rate of girls, thats somehow possible.
