Understanding Basic Probability Concepts

This video tutorial introduces the concept of probability, emphasizing its role in everyday decision-making and statistical analysis. It defines probability as the likelihood of an event occurring and explains its application in various fields such as gambling, insurance, and weather forecasting. The tutorial outlines four fundamental probability rules: probabilities range between 0 and 1, the probability of an impossible event is 0, the probability of a certain event is 1, and the sum of probabilities in a sample space is 1. Practical examples are provided to illustrate these rules.
