Dr. Pepper-

I don’t really know the calculation involved, but using this post of yours:

…and this explanation of nCr (which I think helped me understand it):

I’ll try this:

(8 nCr 3) * ((1/12)^3) * ((11/12)^5)

=

56 * 0.0005787037037037037037037037037037 * 0.64722784850823045267489711934156

=

0.020974976572025986892242036249453

or about a 2% possibility

(fractions derived using the Windows calculator)

Now, here’s homework for the teacher:

1) If the answer is correct but clumsily done, please show the correct way of doing it.

2) If the answer is incorrect, please show where the mistake(s) lie(s).
