nope to both

Damn. Well, that was quite time consuming and I really have no interest in backtracking to find out what I did wrong. Am I even close?
RE: Riddles, brain puzzles and mathematical problems - Froge - 12-09-2012
Not close. Your methodology is wrong.
Edit: Maybe this is a hard question. It might require a bit of knowledge of Stats 101 and high school mathematics.

FAIL I calculated how many wins might ALIAS have. Even though that is wrong too.

Your methodology is wrong.I've never calculated the expected value of events from the point of view of two parties before (I'm grateful I don't have to know how to do that for my math final tomorrow). Anyway, I have no idea how to go about calculating this.

If you give me a minute I may be able to solve it.
EDIT: Actually nope, I don't think I can. Since we are the only people who post in this thread maybe you should just reveal the solution Chronofox.
If you have detailed notes that would be great. If not a general gist of how you calculate it would be helpful.
RE: Riddles, brain puzzles and mathematical problems - Froge - 12-09-2012
I'll give you a clue about part 1 of the game.
ALIAS has more heads than Kman at: 3-2, 3-1, 3-0, 2-1, 2-0, 1-0 where the first value corresponds to the # of heads that ALIAS has and the second value corresponds to the # of heads Kman has.
Kman has more heads than ALIAS at: 1-2, 0-2, 0-1
They have a tie at 0-0, 1-1, and 2-2.

RE: Riddles, brain puzzles and mathematical problems - Bridge - 12-09-2012
Fuck, I forgot to take into account 3-1 and 3-0 and so on. Still, is my method of multiplying ALIAS' chances of getting heads by Kman's chances of getting heads correct?
