(+5)** 8. Three prisoners a, b and c know that exactly two of them are going to be executed, but they do not know which two. Prisoner a knows that the jailer will not tell him whether or not he is going to be executed. He therefore asks the jailer to tell him the name of one prisoner other than a himself who will be executed. The jailer responds that b will be executed. What is the probability that a will be executed before and after the answer is given to him? This is a well known problem. There are solutions on the web, (some of them are wrong). this problem a few times before. If you do not have your own answer, then please do Plus not give to me my solution
