When one rupee coin tosses 3 times the number of outcomes =(HHH, HHT, HTH, HTT, THT, TTH,TTH, TTT)
So total possible outcomes = 8
Player will win the game if outcomes are = (HHH, TTT) =2
Player will lose the game if outcomes are = (HHT, HTH, HTT, THT, TTH,TTH) = 6
Now probability that player will lose the game = 6/8 = 3/4
