This is apparently an interview question from Black Rock.
-------------------------------------$
Murders in a field.
You are guarding 100 murders in a field and you have a gun with a single bullet. If only one of the murderers has a non-zero probability of surviving, he will attempt to escape. If a murderer is certain of death, he will not attempt escape.
How do you stop them from escaping.
//
This question is so interesting so I thought I would give it a go of how I would answer.
I would announce to the prisoners.
That I have a kill switch, if I die the surrounding area is set to explode killing everyone. I walk around with the gun pointed to my head and a rubber band on the trigger finger, meaning if I get incapacitated the gun automatically fires.
I can't tell this solution is stupid, ingenious or completely fucking psychopathic, either way the prisoners aren't leaving.
@fireandforget out of the group of 100 murderers you can't tell which one is going to attempt to escape all that you know is that if they even believe that they have a shred of escaping they will attempt it. So you need to install I guarantee of death before they even attempt to escape.
Also Black Rock worded the question odd. It's simply saying that all 100 prisoners have a chance of escaping if they believe that they can
Meaning technically all 100 prisoners could theoretically attempt to escape at the exact same time.
