This is a story of three prisoners. Al, Bernie, and Chuck are condemned to death, but at the last minute the governor has decided to pardon one of them. He has told the prison warden but on the condition that he is not to reveal who is to go free. The warden likes to bring good news, but true to his word, all he can do is tell them that one of them will go free. They plead for more details, but he has made a promise.

Al has an idea: "I'll speak to the warden privately. One of you, of course, is going to die, so I'll ask him for a name. He won't tell the person involved, but maybe he'll tell me."

Alone with Al in his office, the warden agrees and tells Al that Chuck is one of the ones who is going to die. "Aha," says Al, "I've just increased my chance of survival from 1/3 to 1/2."

10. Indicate whether you or not you agree with Al, and why. If you disagree, state what you think the chances of survival are for Al and Bernie.
