GCSE Maths Question

Now I did my maths exam today and a question I saw on the leaked online official thing showed the probability question (where you have to add up to get the total of 1) I did a sum and found that 0.1125 was green and 0.3375 was for red. The answers are different though BUT my answer still worked out to be 1. (0.15+0.4+0.1125+0.3375 = 1) And you had to make sure that red was three times the amount so to prove that it was right 0.1125 x 3 = 0.3375 are the markers for the paper still going to mark that wrong even though I found a different way? If so then I am suicide because I have so failed :/

The red had to be 4x the amount of green.
0.09x4=0.36
0.09+0.36+0.4+0.15=1

Check my latest thread for answers and marks.
0.3375 is only 3 times more than 0.1125, it asked for 4 times, you are incorrect.
