Answer:
50
Step-by-step explanation:
 
        
                    
             
        
        
        
Any number to the power 0 is 1.
So 10^0 = 1
        
             
        
        
        
Solution - 
The probability of getting 6 from a single roll of a fair dice = 
The probability of getting any other number rather than 6 would be  
 
So when the outcome is 6, then he wins $5 ,otherwise he has to pay $2
So 
E(X) = Expectation value =  ( ∵ $5 gain so +ve and $2 loss so -ve)
                                    ( ∵ $5 gain so +ve and $2 loss so -ve)
=
∴ So Merrill will lose  dollar
