They are shuffled and redealt, this time face down.**

Before looking, the chance is 75% that you have an ace different from your original card.

**Question 2) **And what if the second player also looks at his card and, without showing the card, also truthfully reveals that it is not his original ace? What is the chance that you also have a different ace, given that two players' cards are known to be different?

**Question 3) **Finally, what if the third player also looks at his card and, without showing the card, also truthfully reveals that it is not his original ace? What is the chance that you also have a different ace, given that all three other players' cards are known to be different?
