**Introduction**

The Conditional Frequency Calculator is a handy tool that allows you to find the missing value in conditional probability calculations. It’s especially useful for understanding the relationship between joint relative frequency, marginal relative frequency, and conditional frequency. This calculator simplifies the process, making it easier for you to work with conditional probability.

**How to Use**

- Input two of the three variables: joint relative frequency (JRF), marginal relative frequency (MRF), or conditional frequency (CF).
- Click the “Calculate” button to find the missing value.
- The calculator will use the provided values and the formula (CF = JRF / MRF) to determine the result.

**Formula**

The formula used by the Conditional Frequency Calculator is:

Where:

- CF represents Conditional Frequency.
- JRF stands for Joint Relative Frequency.
- MRF stands for Marginal Relative Frequency.

**Example**

Suppose you want to find the conditional frequency (CF) in a probability scenario. You have the Joint Relative Frequency (JRF) of 0.4 and the Marginal Relative Frequency (MRF) of 0.6. Using the formula, you can calculate the missing value:

So, the Conditional Frequency (CF) is 2/3.

**FAQs**

**Q1: What is Conditional Frequency?**

**A1:** Conditional Frequency (CF) measures the likelihood of an event occurring given that another event has already occurred.

**Q2: When should I use this calculator?**

**A2:** Use this calculator when you need to find a missing value in conditional probability calculations or understand the relationship between JRF, MRF, and CF.

**Conclusion**

The Conditional Frequency Calculator simplifies the process of working with conditional probability by helping you find the missing value in conditional frequency calculations. It provides a user-friendly interface, allowing you to input two out of three variables and quickly obtain the result. This tool is invaluable for anyone working with probability and statistics.
