Final answer:
Christopher uses The Monty Hall problem to show that numerical problems can be complex and not straightforward, challenging common intuitions about probability and decision-making. The correct answer is option: D. He uses the problem to illustrate that numerical problems can be complex and not very straightforward.
Step-by-step explanation:
This question pertains to Christopher’s illustration of The Monty Hall problem in a fictional narrative. The correct answer is D. He uses the problem to illustrate that numerical problems can be complex and not very straightforward. The Monty Hall problem is a famous statistical puzzle that demonstrates how our intuition can be misleading when it comes to probability and decision-making. It showcases that a straightforward choice can have underlying complexity, thus emphasizing Christopher's point that numerical problems require deeper understanding rather than just surface-level calculations.
