    Note that the question is equivalent to "In how many ways can you leave one sock in the drawer" :)

    If you take eight of the socks out of the drawer, there will be only one left. So we can calculate either the combinations for the 8 socks we took or the combinations for the single sock we left.

    The sock left in the drawer can be of any colour. There are nine colours, so there are nine possibilities. Your answer is 9.
