HELP ASAP How many ways are there to put 4 balls in 3 boxes if the balls are not distinguishable but the boxes are?

15 outcomes

Step-by-step explanation:

the balls are all the same so the only differenciating thing is how many balls are in each individual box.

The boxes can have

0,0,4       3 possibilities

0,1,3       6 possibilities

0,2,2       3 possibilities

1,1,2       3 possibilities
