    In a game, players take it in turns to flip two fair coins

    If a player gets 1 head they score 1 point.
    If a player gets 2 heads they score 3 points

    The Object of the game is to get 7 or more points

    Work out the probability of a player getting 7 or more points on their third turn

    The probability is 50/50 each time so to get 7 points you need 3 heads in a row for that you multiply the probabilities together so 0.5*0.5*0.5 which gives you 12.5%. Make sense ?
