Let’s consider an example. Suppose that a man comes up to you and says 
“I have two children. At least one of them is a boy.” 
What is the probability that they are both boys?

Note: we are assuming the man is telling the truth.  
Justification: Any probabilistic analysis presumes that given facts are true.
