    3 songs can be selected in 56 ways

    Step-by-step explanation:

    When the selection has to be made without order combinations are used.

    The formula for combination is:

    C(n,r) =\frac{n!}{r!(n-r)!}

    Here

    Total songs = n = 8

    Sons to be selected = r = 3

    So,

    C(8,3) =\frac{8!}{3!(8-3)!}\\=\frac{8!}{3!*5!}\\=56

    Hence,

    3 songs can be selected in 56 ways
