Need to use the concept of path dependency. Accordingly it is seen that HTT is more likely to win this game.

Since it is a fair coin, no need to think. The probability is the same. Tossing three coins has 8 possible outcomes (2*2*2). HTT and HTH both represent one outcome. Each probability is 1/8.
