Two independent events

A lead has a 30% chance of opening the email and, if opened, a 50% chance of clicking. What is the probability they open AND click?

The twist: you do not solve this yourself. You write the PROMPT you would give an AI to solve it reliably. Grace runs your prompt, checks the AI's answer against the verified result, and scores the rigor of your prompt: did you ask for step-by-step reasoning, unit checks, a sanity check on the result?
