The no. of waya to distribute 20 identical balls into 4 different boxes

Answer»

Each box gets an even number of balls.

I've made some code in python which GAVE me an answer of 286

I tried different METHODS to work this out MATHEMATICALLY and the only one that proved useful is:

2x + 2y + 2Z + 2w = 20

x + y + z + W = 10

С(10+3,10) = 286
