    Number of ways of distribution

    Hi, if we have n different things and we need to distribute them among m different people then how many ways can we do it such that for each of the m persons there is conditions that:
    person 1 can have at least a things and at most b things
    person 2 can have at least c things and at most d things
    .. and so on ?
    Thanks.

    a+1 -------------------------- n-a-1
    a+3 -------------------------------- n-a-2
