You are evaluating a one-roll contract tied to a fair six-sided die. The contract pays you $100 if the die lands on an even number, and costs you $50 if it lands on an odd number.
How would you price a contract that pays out $100 if a rolled die lands on an even number, but costs you $50 if it lands on an odd number?
