Maths Question

That is indeed the answer

This answer is based on a condition that isn't specified in the original question: What happens if the bias is 100%? The answer is only correct for bias < 100%. Very poorly worded question, so I agree with gatso.

Still works for 100% bias.  Both players have a 0% chance and the flips last forever, but theoretically both people still have the same chance of winning so it is "fair".

Has this one been done on here before?

I have a standard coin. But... it is biased to one side. We don't know which side, nor do we know the size of the bias. How can we use this coin to get a genuine 50/50 chance?

It's not a genuine 50/50 chance if it's 100% biased. You can't multiply 0 by anything to get to 50. 0/0 is indeterminate. My point stands .

Edit: To clarify my point - if the question had said, "the same chance of winning", I would accept your response. But it doesn't. 50/50 ≠ 0/0.

Thanks, but are you sure you're on the right forum? This is blonde. People don't just concede points. I want an ARGUMENT, FFS

it's alright, cf will be along in a bit to attach some random caveat that wasn't included in the original question
