    1.They need to toss the coin 2 times.
    2. Whoever person makes the call in the first time has to make the second call just opposite…for e.g if he calls head in the first call ,he must call tail in the second turn.

    The reason for this is that the probability of HT AND TH will always be equal.

  2. hey nice suggestion, I was thinking if he knows the coin is loaded to favour heads then he should choose heads all the time hehehe
