    probability with deck of cards
    What is the probability of drawing 3 cards that are all queens from a deck of cards?

    3 over 54 but then when you simplify it it, it becomes 1 over 18

    The probability of drawing one card that's a queen is 4/52. That's because the deck sarts with 4 queens out of 52 cards. Now, if you are successful with that first draw, you are left with 3 queens in a deck of 51 cards, so the probability of the next card being a queen is:

    3/51

    Hence the probability of drawing two queens in a row is

    4/52 * 3/51

    Now, can you continue this logic to determine the probability of drawing a third queen in a row?
