Ok so here it goes....I will post the answer tonight at 9PM CT.

Ok, so Teanchi and Beanchi are a married couple (dont ask me whose he and whose she)!

They have two kids, one of them is a girl, what is the probability that the other kid is also a girl.

Assume safely that the porbability of each gender is 1/2.

OMG!!! COMPLETELY forgot to post it sorry!!

Here is the answer.....33.333333333%

Here is the reasoning....you can have 4 combos

Boy/Girl
Girl/Boy
Boy/Boy
Girl/Girl

Ok so the boy/boy option is out....So they now have a 1 in 3 chance the next one will be a girl instead of a 2 in 4 chance like there was before....

Does that make sense to everyone? I tried to put it into my own words lol
