Answer:
infinite
Step-by-step explanation:
Let the linear equation in two variables be ax+by+c=0
Put values


Hence for any values it has infinite number of solutions .
including x=1 and y=3 
 
        
                    
             
        
        
        
We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1 
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3
Therefore, 
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.
