It looks like you are writing out the probability of rolling each sum, which is a prerequisite for a solution, but is not a solution itself. And yes,...

As I mentioned earlier, you can try to calculate the total probability of losing instead, and take 1 - P(lose). Either way, you have to set up "small...

As far as I can tell, what you have is not correct. There are a number of issues 1) Rather than picking A = 10 and B = 10 specifically, if you're...

I was! Did you write out P(win on 2nd throw), P(win on third throw), and P(win on fourth throw)? It should be enough to establish a pattern ;)

Uh, ok. Check your assumptions at the door. I understand the problem fine, and can use both systems of measurement fine. The Imperial one is just...

Yeah, both of these probabilities you computed are correct. P(win on first throw) = 7/72 You are also correct that the probability of "his point"...
