ashlea is planning on having 8 children. Determine the probability that all of her children will be girls. If her first 7 children are girls and she is expecting another child, what is the probability that her eighth child will be a girl?

If it is the same sperm donor, I would say the chances are high, that it will be a female. Simple odds...

I don't see how being the same sperm donor will make the odds in favor of another female...

MeekDocile2006,

Welcome to this wonderfully beautiful site, first!

The probability that all will be girls i.e. GGGGGGGG is 1/ = 1/256
If her first 7 children are girls, then -
The probablitiy that her eighth child will be a girl is 1/2

We don't do homework - if you post your answer someone will come along to correct it.

You don't learn anything if we do the work for you.
