Think you know probability?

I'm sure some of you have heard this one before, but for those who haven't, give me your answers:

You are handed a revolver, with two bullets placed in adjacent chambers in the 6-chamber cylinder. The cylinder is spun to a random position and the loaded gun is handed to you. You put the barrel to your head and pull the trigger - an empty click.

Now, you are told that you must pull the trigger one more time. Do you re-spin the cylinder, or just pull the trigger again?

NB. Please do not post explanations for your answer until everyone has had a chance to make up their mind. Also don't bother Googling an answer, it kind of defeats the purpose of the exercise.

Hint: Read the initial conditions carefully, and visualise the situation.

Its obvious - give spanish a call see what he recommends then do the opposite.

Do you laugh at all your own jokes in real life, or just on internet forums

Where is BSD, these days? I hope he's not into cross-dressing.

Excellent, Monty Hall tooled up. Do we need to account for the weight of the bullets or can we assume each chamber has a 1/6 chance of selection? I've actually no idea how revolvers work in this respect. Regardless, it's going to be the second choice.

Easy!

He pulled the trigger again with out respinning.

It depends if you want to improve your chance of survival, or if you fancy topping yourself !

After spending an afternoon reading T2W I'd be definately inclined to re spin the cylinder , but its truly great threads such as this that get you thinking, so with my faith in humanity temporarily restored, I'll pull the trigger.
