Exploring Conditional Probability Concepts

The video tutorial covers basic and conditional probability concepts, using examples with coins, dice, marbles, and student data. It explains how to calculate probabilities for single and multiple events, including conditional scenarios. The tutorial also demonstrates how to use frequency tables and real-world examples to understand probability better.
