|Aces and the Joker|
Aces and the Joker is the 102th puzzle from The Curious Village.
You've scattered a deck of 52 cards over one joker facedown on a table so that you don't know which card is where. Next you start turning the cards over one by one. Assuming that you can't flip the same card twice, what are the percentage odds that you will turn over all four aces before you turn over the joker?
