Exploring Conditional Probability Concepts

The video tutorial covers the concept of conditional probability, starting with the formula and its application. It explains how to use sample space to visualize and calculate probabilities, followed by an exploration of two-way tables to find conditional probabilities. The tutorial concludes with a practical example of using probabilities to make decisions, emphasizing the importance of data analysis in probability.

What is the formula for conditional probability?

• P(A and B) / P(A)

• P(A or B) / P(A)

• P(A) / P(B)

• P(B | A) = P(A and B) / P(A)
