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

i dont know how to do that :(

Answer 7

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

Answer 15

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?

Answer 16

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
