The probabilty that each child get altleast one pen is ?? @FoolForMath there are two formulas, which are: \[(k-1)C _{n-1} \] where k->Total no of non-distinguishable objects n->total no of distinguishable receivers and \[(n+k-1)C _{k} \] Now can you tell me which formula to use in this case and why?

    I still don't get the difference between theorem 1 and theorem 2 in Stars and bars combinatorics. Can you please make it easier for me to differentiate them
