  • subset -

    A subset B of a given set A is a set in which all members of B are contained in A. If one member or more in A does not belong to B, the B is a proper subset of A.

    Example:
    A={cups, glasses, plates}
    B={cups}
    C={glasses, forks}
    then B is a subset of A, and C is NOT a subset of A.
