Next Years Economy

strong weak

CD 6000 6000

Office 15,000 5000

Land 33,000 -17,000

Tech School 5500 10,000

Let V, W, X, and Y denote the payoffs for the CD, office complex, land speculation, and tech school respectively. Then V, W, X, and Y are random variables. Assume that next year's economy has a 40% chance of being strong and a 60% chance of being weak.

a. Find the probability distribution of each random variable V, W, X, and Y

b. Determine the expected value of each random variable.
