Answer:
59/99
Step-by-step explanation:
Since the denominator is the same you add the numerator values for each fraction  27+17+15 = 59
 
        
                    
             
        
        
        
If there are 14 different scenarios that can happen (Blue 1-5, Green 1-6, Red 1-3), and 9 of them are not blue, there is a 9/14 chance that the first pick is not blue. to get percentages, you divide 9 by 14 to get 0.64, or 64 percent chance at not picking blue.
