Clarify the problem by restating it and asking questions to ensure understanding. Break it down into smaller parts, use first principles to derive the solution, and explain your reasoning step-by-step. Verify with a simple example or simulation if possible.
Pro tip: Think out loud and communicate your assumptions clearly; interviewers value your problem-solving process as much as the final answer. If stuck, try solving a simpler version first.
Restate the problem in your own words and ask clarifying questions to confirm assumptions and constraints.
Identify the key components, such as events, sample space, and probabilities, and consider if it can be divided into simpler subproblems.
Decide on an approach: combinatorics, conditional probability, Bayes' theorem, or simulation. Explain why you chose it.
Work through the calculations or logic clearly, narrating each step and checking for errors.
Test the result with a simple case or alternative method, and interpret the answer in the context of the problem.
