You can put this solution on YOUR website!
If NONE OF THE CHILDREN ARE BOYS, this means that EACH CHILD MUST BE A GIRL!

The probability of this happening is %281%2F2%29%2A%281%2F2%29%2A%281%2F2%29.
This answer is 1%2F8. I'm absolutely sure that this is correct, but it doesn't match any of your multiple choice answers. Perhaps you've copied something wrong???
