    1.) Sum the items or the class' frequencies:

    33 + 1,111 + 1,616 + 77 + 22 = 2859

    2.) Divide each class' frequency by the total frequency:

    a = 33/2859

    =.012

    b = 1,111/2859

    =.389

    c = 1,616/2859

    =.565

    d = 77/2859

    =.027

    e = 22/2859

    =.008

    3.) Therefore, the relative frequencies of each class are as follows:

    a =.012; b =.389; c =.565; d =.027; e =.008
