1identical does not make any difference.it is not stated in th question that u cant select 5 identical balls
11For identical balls u can simply plug in the well-known method of integral (non-negative) solutions - as well, that'll reduce the load of cumbersome calculations as one gets from multinomial thorem.

dude soumik why do you always give methods that go over my head???
was this calculation cumbersome?
