A guy deals out 5 cards face down. He tells you that he knows it's a royal flush of spades. He then places the cards back in the deck and throws them into an incinerator. When asked how he knows, he says he read in a book that everytime 5 cards aren't looked at or otherwise determined, they are a royal flush of spades.
You realize there is no way to prove they are not.
Do you believe him?
