1. The problem statement, all variables and given/known data
Consider a collection of 100 oscillators, each with an average of 10 quanta.
a) By what factor would $$\Omega$$(microstate) change if the total energy were increased by a factor of 2?
b) By what factor would $$\Omega$$ change if one more oscillator were added to the original system without changing the total energy?

2. Relevant equations

3. The attempt at a solution
I tried to use (q+N-1)!/(N-1)!q! but it doesn't work...

The answer for a) is '2^99' and for b is 'a factor of 11'

Could someone help me out here?

Thanks a lot !

I have just tried to substituted the value into the equation and it seems the answer is approximately correct a) 2^96.6 b) 10.9 (with N=100, q=1000).
Maybe I misinterpret the question.
