6x6 to find the probability for every single roll which is 36.
Ways to make 5 ; 1+4, 4+1, 2+3, 3+2. 4 ways, therefore it’s 4/36 which simplifies to 1/9
        
             
        
        
        
The biggest common factor number is the GCF number. So the greatest common factor 9 and 14 is 1.
 
        
                    
             
        
        
        
The first y equals -3 and the second y equals -9
        
             
        
        
        
Answer:
