if you are dealt 5 cards from a shuffled deck of 52 cards find the probability that all 5 cards are picture cards please show how to get the answer such 6!C! so i can understand

  • math - ,

    Question:
    Do you consider an ace a "picture" card?

    I will assume you only want the J, Q, and K
    There are 12 of those
    So the number of sets of 5 form those 12 = C(12,5)
    Without restriction, the number of sets of 5 is C(52,5)
    so the prob that your 5 cards are "picture" cards
    = C(12,5)/C(52,5) = 792/259860 = .000305

    If your interpretation is otherwise make the necessary changes.
