Imagine that you are buying a new car and you can buy either a gas powered or an electric powered version of the car. If gas prices are high then the cost of powering the gas car over the lifetime of the car is $15000, but if gas prices are low, then the cost is $10000. If gas prices are high the cost of powering the electric version is $13000, but if gas prices are low the cost is $11000. Both cars cost the same and the probability of gas prices being high is 70%. Draw a decision tree and indicate which vehicle is the better choice
