Re: probabilityeasy oneHi; P(at least 1 six) = 1  25 / 36 = 11 / 36 b) Enumeration is fine but for a gf, here is one. The ways to make an 8 are 2sx^2 and 3x^8. So the answer is 2 / 5. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
