    Combination/Permutation Problem

    If you had a game of scrabble, and there were only 26 letters in the bag (each letter is a member of the alphabet, no repeats) and you were to chose 5 out of the bag and not put them back in, then how many possible selection of letters can you make?


    I don't think the order matters, so would the answer be 26C5?

    Thanks!

    Hello, MattWT!

    If you had a game of Scrabble, and there were only 26 letters in the bag
    (each letter is a member of the alphabet, no repeats),
    and you were to choose 5 out of the bag and not put them back in,
    then how many possible selection of letters can you make?

    I don't think the order matters, so would the answer be: . _{26}C_5 ?

    Yes!
