Question 1138263: A store specializing in mountain bikes is to open in one of two malls. If the first mall is selected, the store anticipates a yearly profit of $ 675,000 if successful and a yearly loss of $ 225,000 otherwise. The probability of success is 1/2. If the second mall is selected, it is estimated that the yearly profit will be $ 450,000 if successful; otherwise, the annual loss will be $ 135,000. The probability of success at the second mall is 3/4.
a. What is the expected profit for the first mall?
b. What is the expected profit for the second mall?

You can put this solution on YOUR website! This would be half of the difference of $225000
E(X)=0.5*(675)-0.5*225=337.5-112.5 or $225 thousands or $225,000.
The second is 450*(3/4)-135(1/4)=$303.75 thousands or $303,750.
