I toss two coins and look at the outcome.
I then tell you that at least one of the coins is showing up as "tails". What is the chance that the other one is showing "tails" as well?
(In reply to re(2): It's not 1/3 the way the problem was posed.
Make that "tails" in my preceding post, but the argument is the same.
