What is the Conditional Probability Calculator?

The Conditional Probability Calculator is a simple tool that helps users find the probability of event A occurring given that event B has already occurred. By entering the joint probability P(A and B) and the probability of B, the calculator applies the conditional probability formula to compute P(A|B). This tool is useful for students, teachers, and anyone studying probability, statistics, or real-world situations where one event affects the likelihood of another.

How to Use:

1. Enter P(A and B): Provide the joint probability of both events occurring together.
2. Enter P(B): Input the probability of event B, ensuring it is greater than 0.
3. Click “Calculate”: The calculator will compute the conditional probability P(A|B).
4. Review Result: The output shows P(A and B), P(B), the calculated conditional probability P(A|B), and a simple interpretation to help understand the meaning.
