Exploring Conditional Probability Concepts

The video tutorial introduces the concept of conditional probability, explaining how to calculate the probability of an event given that another event has already occurred. It uses examples involving cards and tables to illustrate the concept. The tutorial emphasizes the importance of the 'given' statement in changing the sample space and provides several practice problems to reinforce understanding.

How does a 'given' statement affect the sample space in conditional probability?

• It reduces the sample space

• No effect

• It changes the probability outcomes

• It increases the sample space
