Monte Carlo methods are a type of computer simulation that use random numbers to imitate real-world situations. They are used to figure out the chances that an event will happen, or the probability of something happening. For example, if you want to know the chances that it will rain today, a Monte Carlo method can help you figure it out. The method works by collecting lots of random numbers from different sources, such as weather data and analyzing these numbers to figure out the chances of rain. This way we can get a good guess of what is likely to happen without having to wait and watch the entire day.
