Answer:
80% chance
Step-by-step explanation:
 
        
             
        
        
        
I think that A would work, considering they're not looking for movie theaters prices.
        
                    
             
        
        
        
The general equation of the sine function y=f(x) is defined as 
 
where A is the Amplitude
 B represents the frequency of the function with period equals 
 C represents the Horizontal shift, For Phase shift= -C/B
 D represents the Vertical shift. 
The data given that the amplitude of the function A=6
 
Vertical shift 
 Horizontal Shift 
Now plug in  in the general equation of sine function, we get
 in the general equation of sine function, we get
 
 
        
             
        
        
        
The 9 combinations that exist for two movements:
R,R
R,L
R,U *
L,R
L,L
L,U
U,R *
U,L
U,U
Walker would only be able to make it to (1,1) with only 2 of these combinations.
So if he were only allowed to make two movements, his chances of arriving at (1,1) would be 2/9.
