You are trying to decide whether or not to book a cheap flight to fly home from NCSU after your final exams

You are trying to decide whether or not to book a cheap flight to fly home from NCSU after your final exams, but you're not sure when your last exam will be.

You think there is a 20% chance that your last exam will be scheduled after the last day that you can get a seat on the cheap flight. If it turns out that your last exam is scheduled after the last day that you can get a seat on the cheap flight, then you will have to cancel the flight, resulting in a loss to you of $150. If you can take the cheap flight home you will save $100.

Question 1. If you book the cheap flight, what is your expected gain?

Question 2. If you book the cheap flight, what is the standard deviation of your gain?
