Red because you'll just count the total nos. of the apple and it is 30 then count the nos. again by colors                                                                                                                                                                                                                    Note: Reduce to lowest term and if you get the 1/3 the color you place in the numerator is the answer

Yellow - 2/30 
Yellow (Reduced) - 1/15 

so yellow is not the answer...

Green - 15/30
Green (Reduced) - 1/2

Green is not the answer

Orange - 3/30
Orange (Reduced) - 1/10

so Orange is not the answer

Red - 10/30
Red (Reduced) - 1/3

so Red is the correct answer

I'm 100% sure...!!!
