Answer:
Neither
Step-by-step explanation:
They both have the same probability because 2/5 and 0.4 have the same value.
 
        
             
        
        
        
<span>If y varies directly with x, the formula of the equation is y=ax, where a is a constant. 
 y=ax 
 (21)=a(7) 
 a=3 
 y=ax 
 y=(3)(-1.66) 
 y=-4.98, x=-1.66 
 If y varies inversely with x, the formula of the equation is y=a/x, where a is a constant 
 y=a/x 
 9=a/2.5 
 a=22.5 
 y=22.5/x 
 y=22.5/-0.6 
 y=-37.5 
I hope this helped! =)
