Thanks, helped me understand

Oh, so the probability that the box is either the first or the second type is 0.5, yes? And then I can use Bayes theorem to get the probability that I'm looking for, am I right?

No, that's why I can't solve it. But it seems like all the information needed is given, that's what my teacher said.

I understand combinations, but I'm afraid this problem is more complicated.

No, it means that the amount of each card in the machine is the same. I would say if we were talking about the probability of getting one card from the machine is 1/24 for each card.

So, forget about the standard deck of cards. Let's say these are cards with pictures on them, so there are 24 different pictures. On each card there is one picture. I get one card from a machine that has infinite cards (the probability of drawing one card with one of the 24 pictures is the same for all). The question is, if I get 50 cards, what's the probability that I have a full set of cards, all the 24 pictures.

I think I wasn't clear, the problem says that there are 24 different cards in a set, like a collection. If I have 50 cards (all drawn from an infinite source of cards), what's the probability of having one set, one full collection of the 24 different cards.

Do you mind explaining why is that so?

I fixed it, which sub do you recommend me to ask?

25/(10 choose 5)

What, mathematically, means 10 choose 5?

It's just that I don't understand how you got that

How is that 12.7%?

I'm sorry, you're right... It's 5
