Here is a prblem based on probability. It is supposed to be really difficult. I am still not sure about the correct answer.

Here is the problem-
There are three prisoners A, B and C. A knows that two of the three are going to be released. Obviously the probability that A is released is 2/3. Now A becomes curious and asks the jailor,"Which two of us will be let go?"
The jailor replies,"Well, I cannot tell you that, but B is going to be set free. That is all I can tell you."
A gets disappointed and goes back to his cell and starts thinking about the new probability of his discharge.

Has the probability really changed? If no, why? and if yes why and what is the new value?

If you know the solution, please send it to me. I will post it here along with your name of course :)
