hockey stick identity problems
1.We have 8 pieces of strawberry candy and 7 pieces of pineapple candy. In how many ways can we distribute this candy to 4 kids?
2. In how many ways can we distribute 13 pieces of identical candy to 5 kids, if the two youngest kids are twins and insist on receiving an equal number of pieces?
3. 4 students are running for club president in a club with 50 members. How many different vote counts are possible, if everyone is required to vote?

Re: hockey stick identity problems
Hi;
Those can be handled with generating functions or solutions to a diophantine equation using x's and dashes.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: hockey stick identity problems
The problem was that I thought that each of the 4 students needed at least one vote. This is untrue, some could get 0 votes.
