Re: Can't find the formula for this assignemnt problem



I have solved my own problem. I think that it is COMB(Dtotal,D)*COMB(Atotal,WD)
and SUM(D=0 to W ,COMB(Dtotal,D)*COMB(Atotal,WD))= COMB(Dtotal + Atotal ,W).
Does this hold for fractional values of Dtotal, Atotal W, and D?

How many ways can W objects be assigned to Dtotal + Atotal objects where the number of W objects are assigned to D? Example : What are the number of ways that five candy bars can be given to a group of twentyseven girls and thirteen boys where exactly three candy bars are assigned to any three boys?
