not really. I've been trying to solve it that way all this time. I'm getting weird results.

From \[\large ^n C_r = \cfrac{n!}{r! (nr)!} = \frac{40!}{12!(4012)!} = \frac{40 \times 39 \times 38 \times...}{(12 \times 11 \times 10 \times ...)(28 \times 27 \times 26 \times ...)}\]

That is wrong all of you I think its 12 times 40 its simple probability i think

It's the right answer, yeah. But it's damn confusing having to work with numbers like 815,915,279,999,999,744,392,488,672,368,848,648,400,776,424,296 _ so I must've made a mistake at some point.
