Q: You stand blindfolded in front of a table. you are told that there are 32 cards with the number up and an unknown amount of cards (so it's not sure it's 52) with the number down. Is there a possibility that you can divide the cards in two groups so that both groups have the same amount of cards with the number upwards.
Note: there is a chance that the answer is no, but that would be really stupid. It's a question from my gf school for 15 to 16 year olds

better formulation, because as it is now, your question is complete shit

flip the first 32 cards.

these 32 cards now have the same number of face-up cards as there are on the rest of the table.

You stand blindfolded in front of a table on which there lay a lot of playing cards. You are told that 32 cards lay with the (i don't know how to say it, the side displayed in the picture)-side up and an unknown number with that side down.
Can you divide these cards in two groups so that there is an equal ammount of cards with the (pic)-side up, without taking of the blindfold

i don't think you know the difference between the first cards and the others, otherwise you could just divide those

lay face up vs face down

Without looking I think the answer is no.
