FYI, there is a multinomial command in Xcas for probability, it has an additional 2nd argument, the list of probabilities. It would perhaps be interesting to include in the Prime.

ok, I'll try to re-write the program without input, in effects...

Yes, it would be interesting to include multinomial in the Prime, I hope the Team would seriously consider the idea to do that!

About combinatorics, in the CAS there are also functions for combination with repetition and permutation with repetition?
I defined to function to have them in the Prime (simply -> comb(x+k-1,k) and x^k)...

I'm thinking also to write something to treat Stirling numbers.
