An interesting problem was recently brought to my attention.
The question.......what should you do?

When you first picked, you had a one in three chance of being right.

With one board removed, your pick 'still' has a one in three (33 1/3 %)
chance of being right.

However, with only two boards left, you can chance your chances. If you pick
a different board (the remaining) you will now have a one in two (50%)
chance of being right. it behooves you to re-pick.
