In an amusement arcade there is a horse race with horses coloured red, yellow and green. Only one player can play this game at any time and the outcomes of each race are independent of previous races. You can either bet 10p or 20p. If you bet 10p then each horse is equally likely to win. If you bet 20p the corresponding probabilities are 50% (red), 30% (yellow) and 20% (green). Three times as many people bet 10p as do 20p. What is the probability a red horse wins? O 0.375 O 0.267 O 0.367 O 0.308
