Hello,

I am currently working on the current example and need some pointers/help with it:

What is the minimum number of children (N) a couple should have in order to achieve both a male and female child with 99% probability? (Given the presumptions that the chances of having either a boy or girl is 50/50, and each sex at birth is independent of previous births)

Any help would be great!!

Thanks

What's the number that produces a probability of having all girls that is less than 1%?
