    we have 13 black cards, so the requested probability is: \(favorable\;outcomes/possible\;outcomes=...?\)

    favorable outcomes=13, possible outcomes=52, so probability=13/52=...?

    would that question be experimental or theoretical ? @Michele_Laino

    lets say i ask you topull a black king out of the deck of cards, and you keep it, then i ask you to pull another black card, would the second pull be independent or dependent?

    the probability to get a black king is 2/52=...? If, after the first draw, I put the card into the deck, then the the first draw and the second draw, are independent events
