When a coin of one rupee is tossed three times, the all possible outcomes are given as :
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT.
Total number of all possible outcomes = 8.
Let the probability of getting same outcomes be (A).
The favourable outcomes of occurring same outcomes are HHH, TTT.
∴ The number of favourable outcomes = 2
∴ The probability that Haneef will win the game
P(A) = \(\frac { 2 }{ 8 }\) = \(\frac { 1 }{ 4 }\)
Let the probability of not winning the game be P(\(\overline { A }\))
∴ P(\(\overline { A }\)) = 1 – P(A)
P(\(\overline { A }\)) = 1 – \(\frac { 1 }{ 4 }\) = \(\frac { 3 }{ 4 }\)
Hence, the probability that Haneef will loss the game = \(\frac { 3 }{ 4 }\)
