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.

Your answer of 9 may be the median position.  The distribution of 1st queen position has a negative skew.
