# Brain Teasers for Adults #5 - Live Or Die Probability Puzzle

Difficulty Popularity

Hussey has been caught stealing goats, and is brought into court for justice.

The judge is his ex-wife Amy Hussey, who wants to show him some sympathy, but the law clearly calls for two shots to be taken at Hussey from close range.

To make things a little better for Hussey, Amy Hussey tells him she will place two bullets into a six-chambered revolver in successive order.

She will spin the chamber, close it, and take one shot.

If Hussey is still alive, she will then either take another shot, or spin the chamber again before shooting.

Hussey is a bit incredulous that his own ex-wife would carry out the punishment, and a bit sad that she was always such a rule follower.

He steels himself as Amy Hussey loads the chambers, spins the revolver, and pulls the trigger. Whew! It was blank. Then Amy Hussey asks, 'Do you want me to pull the trigger again, or should I spin the chamber a second time before pulling the trigger?'

What should Hussey choose?
