About this test
Expected-value problems applied to decisions under uncertainty — bets, investments, insurance, and decision trees — the reasoning behind quant-trading and finance interviews. Distinct from Probability Reasoning I and II: those calculate a probability or count a sample space; this one uses expected value to decide between options, including when expected value alone isn't the whole answer.
