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%.
