Card shuffling problem Anonymous 17/11/26(Sun)11:40 No. 16584 ID: e4210a

File 151169285858.jpg - (527.09KB , 1200x1200 , PromotionalDeckOfCardsAndCase572.jpg )

I've got a deck of C cards. I shuffle it and deal D cards.

I shuffle it again and pick two cards at random.

The first card is not to be reshuffled in the second iteration.

The second will be exempt from the reshuffling and be part of the second iteration.

How many iterations will it be before it's a 100% probability of identical results?
