1. What is the historical genesis?Emerged from 17th-century studies of games of chance by Pascal and Fermat
2. What is the applications in AI?Crucial for machine learning algorithms, pattern recognition, and predictive modeling
3. Why did people study probability?People first studied probability while playing games like dice and cards. They wanted to figure out how to share winnings when a game stopped early.
4. How do we calculate the chance of something fair?If every outcome is equally likely, we count the good ones and divide by all possible outcomes. That gives the probability.
