246+315=561
 
        
             
        
        
        
Step-by-step explanation:
a probability is always desired cases over total possible cases. 
so, we have actually 8 systems (5 + 3) we can pick from. 
therefore, the total possible cases are 8.
the desired case is in this question to pick one of the 3 Wii consoles. 
the probability to pick a Wii is therefore
3/8 = 0.375
 
        
                    
             
        
        
        
To find the number of non-defective chips, we simply use this equation:
2,000 * 4/5
8000/5
Now you simply divide:
1600
1600 chips aren't defective
