| killerzX said: my natural response would be 25% of course, but then i started over thinking it. there are only the possible outcomes to flipping 2 coins. getting one head and one tail, getting 2 heads, or getting 2 tails. so in a way it seems its a 1 in 3 chance. i know its stupid but that seemed kinda interesting to me to think about. |
The thing is, "one heads and one tails" are actually two different result: "Head - Tail" and "Tail - Head", so you have 4 possible outcomes: "Hea - Head", "Head - Tail", "Tail - Head", "Tail - Tail". Two of which involve one of each, so 2/4 = 1/2 is the chance of getting one of each out of an honest coin.

None of this really matters since they have no information o nthe coin (actually it's very likely that it was at least implied it was honest): It might be heavier on the tail side just as well as it might on the heads side, so all of these unkowns cancel each other.
