Assuming boys and girls are equally likely, find the probability of a couple having a baby boy boy when their fourth fourth child is born, given that the first three three children were all boys all boys.

So then the probability of fourth child being boy is 1/2, since boys and girls are equally​ likely.

Hope this helps.

You have to find the angle i don’t know if i i try
