Explain why the value of a matrix game is positive if all of the payoffs are positive.   A. If the matrix game is strictly determined and all of the payoffs are​ positive, D=(a+d)−(b+c)will be negative and ad−bc will be negative.​ Therefore, the​ value, v, will be positive. If the matrix game is nonstrictly​ determined, and all of the payoffs are​ positive, the saddle value will also be positive.​ Thus, the​ value, v, is positive.     B.

Question

Explain why the value of a matrix game is positive if all of the payoffs are positive.

 

A. If the matrix game is strictly determined and all of the payoffs are​ positive, D=(a+d)−(b+c)will be negative and ad−bc
will be negative.​ Therefore, the​ value, v, will be positive. If the matrix game is nonstrictly​ determined, and all of the payoffs are​ positive, the saddle value will also be positive.​ Thus, the​ value, v, is positive.
 
 
B. If the matrix game is strictly determined and all of the payoffs are​ positive, the saddle value will be negative.​ Thus, the​ value, v, is positive. If the matrix game is nonstrictly​ determined, D=(a+d)−(b+c) will be positive and ad−bc will be positive.​ Therefore, the​ value, v, will be positive.  
 
C. If the matrix game is strictly determined and all of the payoffs are​ positive, D=(a+d)−(b+c) will be positive and ad−bc will be positive.​ Therefore, the​ value, v, will be positive. If the matrix game is nonstrictly​ determined, and all of the payoffs are​ negative, the saddle value will be positive.​ Thus, the​ value, v, is positive.
 
D.If the matrix game is strictly determined and all of the payoffs are​ positive, the saddle value will also be positive.​ Thus, the​ value, v, is positive. If the matrix game is nonstrictly​ determined, D=(a+d)−(b+c)
will be negative and ad−bc will be negative.​ Therefore, the​ value, v, will be positive.
