Probability Math Question (Word Problem)?
Question:
You and two other prisoners (3 total) are being held in a prison for a most heinous crime. One of you is going to be executed and the other two are going to be set free. You call over one of the guards and ask him if he knows who will be executed and who will not. He says he isn't aloud to tell me any information about myself but can answer a question about the other two, but will answer only one question. You agree and ask him what the fate of unknown prisoner #1 is, and he says that he is going to live.
What is the odds of you being executed???
Answers:
Is the answer 1/3 or 1/2. You always knew that one of the unknown prisoners was going to have to be set free, so should they even be counted???

this is a variant from the Monty Hall problem called the Three Prisoners problem. Chances of being pardoned, now knowing prisoner #1 is going to live, are 1/3. The detailled answer is in the sources.
