You are driving to a party. You know that at your current speed, you will arrive at your destination in 8 minutes, but you also know that you will have to pass through some lighted intersections. There are four lights on the way to the party. mod * X Three of them are biased in your favor; there is only a 30% chance you will be caught at a red light, and if you are stopped, then it will add 40 seconds to your trip. The fourth light is horribly biased. There is an 80% chance it will stop you and it will add 60 seconds to your trip. What is the total expected time of your trip?
