Does anyone know the odds of having Two girls as children as opposed to two males or one male and one female? I say it is 25 percent but my friend says it is 33.3 percent. Can anyone clarify?

Thanks!

You are correct. Assuming tht boy and girls are equally probable each time, which is almost true, then the eqully likely outcomes are

boy, boy

boy, girl

girl, boy

girl, girl

Only 1/4 of the possiblities are 2 boys or 2 girls. That is the probability for each: 25%. There are 2 out of 4 ways of haing one of each, so that outcome probability is 50%.
