Answer to July trivia: To spin or not to spin?

Because the bullets were loaded consecutively, you will also have four consecutive blank chambers. Since your friend is still alive, her chamber must have been one of those four. In the diagram on the left, that will be A, B, C or D.

A revolver works in such a way that it will rotate to the next chamber every time you squeeze the trigger.

Hence, out of the 4 possible empty chambers, 3 of them will gurantee you safety if you squeeze again without spinning. You then have a 75% chance of surviving.

If you spin again however, your chances of survival are 4 out of 6 which is 66%.

Squeezing the trigger without spinning therefore leaves you with a higher chance of survival.

Here is the link to the question in case some of you forgot.
