There are six unloaded die.
Each has been rolled out of your sight and hidden behind a cup.
You are informed that no more than one of them landed a 6 - but
it may be that none of them did.
You are going to remove the cups one at a time.
Before you do, you label each cup with letters A to F.
This designates the order in which you will remove them.
You have complete discretion which cup is assigned each letter,
but once labeled they must be removed in alphabetical sequence.
Having labelled them, it is time to remove the cups accordingly from A to F.
If one of the dice landed as 6, under which cup is it most likely to be found?
