Homework Statement
{(-3,-4),(-7,2)} Find the value of the game (basically saying find x*)
Homework Equations
E((x,1-x), 1)=E((x,1-x),2))
The Attempt at a Solution
Basically I used dot product of (x,1-x) and column 1 (-3,-7). I got 4x-7 for that, which is my E((x,1-x). Then I found the dot product of (x,1-x) and column 2 (-4,2) and got -6x+2, which is my E((x,1-x),2)). Set them equal to each other to get my x, and got x=9/10. My Y is 1-x, which is 1/10. Therefore my x*=(9/10,1/10). The back of the book says my x* is (6/10,4/10), so I don't know what the hell I did wrong. I hate this class.
