Assume the birth of a boy or a girl is equally likely. The probability that a single child is born a girl is 1/2. What is the probability that the next child born to the same familiy will also be a girl?

OpenStudy (anonymous):

wouldn't it be also 1/2?

OpenStudy (anonymous):

are you given the first child is a girl?

OpenStudy (anonymous):

I think so but i wasnt 100% sure. Thanks(:

yeah, it's 1/2. Unless you meant one of them girl, and then find the probability of the other one being a girl, then it would be 1/3
