Question
Suppose you want to use a decision tree to decide whether to buy Machine A or Machine B. The
right choice depends on the level of demand, which may be high or low. The probabilities of having
high and low levels of demand are 0.6 and 0.4, respectively. The payoff table is as follows:
High Demand Low Demand
Buy Machine A$21,500
Buy Machine B$10,532
$5,443
$8,520
What is the expected value of the decision "Buy Machine A" in dollar amount? Answer with two
decimal places (e.g., 1,200.21), if your answer involves any decimals. Provide only the number (do not
put "$").
