$\huge \fbox \red{❥ Question}$

In a game, a one-rupee coin is tossed three times and the result is recorded every time. Haneef will win if he gets at least two heads. Calculate Haneef’s probability of losing the game.​

Answer 1

Sample space = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

Outcomes when he does not choose 3 heads or 3 tails = {HHT,HTH,HTT,THH,THT,TTH}

Probability of losing = 6/8 = 3/4
