Let
EV----------> <span>expected value
</span>
we know that
EV = (Probability of Winning)*(Value of Winning) + (Probability of Losing)*(Value of Losing)
so
EV=0.04*(200)+0.96*(-14)-----> EV=8+(-13.44)-----> EV=-$5.44
So
she expects to lose $5.44 every time she plays (this is on average)
the answer is
-$5.44
