Exercises: Use Probabilities to Make Fair Decisions
Work through each section in order. A decision procedure is FAIR when every option has exactly the same probability of being chosen. For design problems, describe the mapping and state each option's probability. When a device's outcomes do not divide evenly among the choices, use a divisible range or rejection sampling (reject the leftover outcomes and redraw), and verify each choice has probability $\frac{1}{k}$.
