Odds and Expected Value Interview Questions
Odds and expected value interview prep for implied probabilities, fair odds, payoff EV, and odds-format mistakes.
Candidates practicing betting-odds and payoff prompts.
Odds encode payoff and probability
Odds-style prompts ask you to connect probability, payoff, and fair value. Clarify the odds format before calculating.
Implied probability
A fair price or odds quote implies a probability at which expected value is zero before fees or margin.
Concrete example
If a toy contract pays 1 dollar when an event happens and costs 0.25 dollars, the break-even implied probability is 25 percent.
Expected value from odds
Compute the payoff if the event happens, subtract the cost, and weight by your probability model.
Fair versus favorable
Fair odds make expected value zero. Favorable odds are favorable only relative to a probability estimate and assumptions.
Common mistakes
Candidates often confuse payout, profit, and price. Expected value should use net payoff.
