Challenge #3 – The Devil’s Tail

The devil has two fair coins with one side Heads; the other, Tails. He tosses both of them, has a look, and tells you:

“At least one of the coins is Tails”

He then asks you if you’d like to bet if both of the coins are Tails.

What is the most likely?

  • Both tails?
  • One is heads?
  • Can’t tell?
