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.
the possible cases are as follows-
1 2
a ------------------------------- n-a
a+1 -------------------------- n-a-1
a+3 -------------------------------- n-a-2
..................................................
.................................................
b -------------------------------------n-b
proceed in this way for the other case also at last u will find a common between the 2
