Calculating Conditional Probabilities

The video tutorial explains conditional probability, which is the probability of an event B occurring given that event A has already occurred. It introduces the formal equation for conditional probability and provides examples to illustrate the concept. The examples include rolling a die, smoking and lung cancer, and drawing cards from a deck. Each example demonstrates how to apply the conditional probability formula to calculate the probability of an event given a certain condition.
