If sample size is a problem then do it more than 100 times. But it's the same principle.
You don't know what the unfair side % is though, and your method doesn't give you a single result at the end (i.e. "heads" or "tails") unless I've misunderstood.
Oh if we don't know what the unfair % is then I have no idea how to solve this problem unless it's some kind of trick question or something.
EDIT: Wait can't we just flip it so many times that we can find the unfair % advantage through statistics and a huge sample size?
By the way I do know that given a normal coin it's more likely to lend on heads than tails because of the indentation. But we're assuming here that it's 50/50 to begin with before the unfair advantage is added right?
