Re: Probability Help!
I'm not good at this, but don't you have to include all these terms in b):
8/36*8/36*28/36 + 8/36*28/36*8/36 + 28/36*8/36*8/36
= 3 * 8/36*8/36*28/36
The logic being that you can hit 7 or 11 at toss 1 & 2, 1 & 3 or 2 & 3.
Warning: It's 5 AM and I'm tired, so this could very well be plain bollocks.
