    The correct question is

    A certain lottery has 34 numbers. in how many different ways can 4 of the numbers be selected? (assume that order of selection is not important.)

    we know that

    C=n!/[ (n-r) !*r!]

    n=34

    r=4

    then

    C=34!/[ (34-4) !*4!]=34*33*32*31/[4*3*2*1]=46376

    the answer is 46376
