Dice Probability quant interview practice.

Dice questions provide a compact setting for testing counting, conditioning, expected value, optimal stopping, and distributional reasoning. This reviewed collection includes sums, parity, repeated rolls, ordered outcomes, altered faces, and decisions about whether to keep or reroll a result. The first task is to determine whether the dice are fair, independent, distinguishable, or modified by an earlier event. For sums and patterns, enumerate through generating functions, case tables, or symmetry rather than relying on intuition. For stopping decisions, compare the certain payoff with the conditional continuation value. The small state space makes verification practical: candidates can check that probabilities sum to one, compare extreme cases, or reproduce a result by direct enumeration. The aim is to build fast but explicit reasoning that transfers to less familiar discrete probability settings.
