### Problem 640

I know that this problem is rather new so I try to ask in a way that doesn't disclosure useful information. Suppose that the game described in this problem is played with a wheel with N pockets (N=2 and N=6) of equal size. For N=2 the expected number is 5.673651. The more precise value would be (I hope) 5.673650793650... (without rounding), so the eighth to twelfth digits after decimal points are 93650. Can anybody confirm these values for eighth to twelfth digits (all without rounding)?

N=2: 93650
N=3: 16302
N=4: 53254
N=5: 93356
N=6: 95798

Your values for N=2 or 3 are correct. The rest are incorrect.

### Re: Problem 640

It seems I'm having the same problem as tuple, as I get those answers too.

Edit: Solved it now. I had made an assumption that was not true in every situation, and from reading the problem's thread, many others did so too.

@jaap, may I PM you my assumptions and a question? I believe I'm having the same difficulty tuple describes.

N=6: 95798
glad I'm not the only one who gets this highly accurate wrong answer
back to the thinking board, i guess...

I did the same mistake.
Thanks for this post. It confirmed that it wasn't a precision error.
