Laura is looking for a way to save money this year on her medical expenses. insurance is starting to get expensive, and her budget is tight. she figures that she has a 75% chance of needing to visit the doctor and get medication once in the winter, for a total of about $400. she also figures there should be some room in the budget for emergencies, so she estimates a 5% chance she will need to spend $300 at an emergency room.
is it reasonable for laura to set her medical budget at $300 for the year?
