Let’s use weather as an illustrative example.
Our weather has three states: sunny, cloudy, and rainy. We want to predict what the weather will look like in the next hour. A Markov Chain would indicate the probabilities of going from one state to the next.
If it’s sunny out, we could say that there’s a 33% chance of it staying sunny, 33% likely to become cloudy, and 33% likely to become rainy.
Now, these probabilities can change depending on what state you’re currently in. If it’s cloudy, maybe the probabilities are like 10% chance of getting sunny, 20% chance of staying cloudy, and 70% chance of becoming rainy.
You can visualize these probabilities using arrows like [this.](https://www.vatsalp.com/post/markov-chain/fig2.png)
