A standard deck of 52 cards contains,
inter alia, four Queens.
After a perfect shuffle, one turns cards from the top one after another, until the first Queen appears.
Please provide your justified estimate at what step will the 1st Queen appear.

I don't know where I got the idea there'd be four perfect shuffles; there's only one mentioned.
Depending on the type it's position 37 or 38.
But now that I think again, that was based on the aces being on top. But the procedure of turning over the cards starts from what was the king side. The positions are 15 or 16 counting from the back.
Again wrong: we want the last when counting from the front, not the first. It's 9 or 10, depending on the type of interleave.
