    [SOLVED] Organized Counting

    hey i am stuck really bad on this question, can any one help please

    a) In how many ways could you choose two fives, one after the other, from a deck of cards?

    the answer at the back is 12, but i do not understand how its 12.

    I got 16 as my answer i did 2^4 since there are 4 5s in a deck.

    There are 4 fives, but you won't be replacing the first five you draw (it would be impossible for your 2 fives to both be the five of spades)

    There are 4 options for your first card drawn, but then there are only 3 options for which five you will draw next.

    4*3=12
