How many different ways can you score 10 points in a basketball game?

How many different ways can you score 10 points in a basketball game?

I counted 14, but I'm not sure if I am missing one.How many different ways can you score 10 points in a basketball game?
Doing it in an orderly fashion is the best way to see you got them all.

Use higher numbers as much as possible, then go to lower ones.



3 3 3 1

3 3 2 2

3 3 2 1 1

3 3 1 1 1 1

3 2 2 2 1

3 2 2 1 1 1

3 2 1 1 1 1 1

3 1 1 1 1 1 1

---- that exhausts the 3's ---

2 2 2 2 2

Then can replace each of the 2's with 1 1 (5 more ways)

--- that takes care of the 2's ---

all 1's



Summary:

8 using 3's 2's and 1's

5 using 2's and 1's

1 using all 1's



Total 14.

You can have 3 points, 2 points or 1 point

10 = 2+2+2+2+2

10 = 3+3+2+2

10 = 1+3+3+3

10 = 3+3+2+1+1

10 = 3+3+1+1+1+1

10 = 3 + 2+2+2+1

10 = 3+2+2+1+1+1

10 = 3+2+1+1+1+1+1

10 = 3+1+1+1+1+1+1+1

10 = 2+2+2+2+1+1

10 = 2+2+2+1+1+1+1

10 = 2+2+1+1+1+1+1+1

10 = 2+1+1+1+1+1+1+1+1

10 = 1+1+1+1+1+1+1+1+1+1

This is 14 indeed if the order plays no role.

If you have to take the order into account,

the number of possibilities is much bigger.
