Monte Carlo Simulation - Lesson Exercise - Quiz Questions
Test your understanding of Monte Carlo simulation techniques, using random sampling to estimate values like pi, and how the law of large numbers improves accuracy.
2. In the geometric probability model for estimating $\pi$, the true theoretical ratio of the square area to the circle area is:
- A. $1 : 1$
- B. $4 : \pi$
- C. $2 : 1$
- D. $3.14 : 1$
3. [Calculation] In a simulation, if a total of $1000$ points were thrown and $785$ of them fell inside the circle, the estimated value of $\pi$ is approximately:
- A. $0.785$
- B. $3.14$
- C. $4.00$
- D. $3.14159$

- B. The random number generator is unstable
- C. When the sample size is too small, accidental error dominates
- D. The result is wrong

- A. $10$ times
- B. $20$ times
- C. $100$ times
- D. $1000$ times
