Suppose we have a deck of cards from two sets of cards (104 or 108 cards).
What is the expected position of the second, let's say, spade ace ?
Any idea ?
I am trying to figure out something for a card game Gong Zhu (en.wikipedia.org/wiki/Gong_Zhu), a Hearts variant in China.
I posted this question on mathoverflow and immediately got put on hold as off-topic :( Seems a very serious math site there. Hope someone here can answer my question. Thanks.
