Two men are walking down the street. Man number one says 'I have two children, a boy and a girl, it is the boy's birthday today'. Man two says 'I also have a boy who's birthday is today, I also have two children'
Now the question is simple.
What is the probability that man two's other child (the one who's birthday is not today) is a boy?
Yes, this is not a trick question, there are four children involved.

I thought it was going to be; "What is the probability that the other man is that boys father?" |

That was a guess as I suspect it is one of those sort of questions

I reckon it's got something to do with a divorce.
The proper dad is talking to the step-dad of the same children

25% if not 12.5%
If they're wrong, I give up.
