  • RE: Tossing old gold coin puzzle
    Curious Asked on 1st August 2016 in Puzzles.

    Lets assume probability of H is x and that of tail is 1-x. We can see that the probability  of coming HT and TH is same which is x(1-x).
    So The two guys can chose one of the two cases(HT or TH)  for each of them. And start flipping the coin:
    if HH came then the cycle restarts.. and same for TT.
    Hence HT and TH can be obtained equiprobably.
