}
```

Certainly! The provided code appears to be JavaScript functions for handling probability calculations based on different scenarios: single probability calculation and multiple probability calculations. Let’s break down the code:

`function setCalculationType(calculationType) { ... }`

This function is designed to toggle between the input forms for single and multiple probability calculations. It takes a parameter

`calculationType`

, which is expected to be either ‘single’ or ‘multiple’.

- It retrieves references to the single and multiple probability forms using
`document.getElementById`

.- If the calculation type is ‘single’, it removes the ‘hidden’ class from the single form and adds the ‘hidden’ class to the multiple form, making the single form visible and the multiple form hidden.
- If the calculation type is ‘multiple’, it does the opposite, hiding the single form and showing the multiple form.

`function calculateProbability() { ... }`

This function is responsible for performing the actual probability calculations based on the selected calculation type.

- It determines the current calculation type by checking if the single form is hidden. If it is hidden, the calculation type is set to ‘multiple’; otherwise, it’s set to ‘single’.
- For ‘single’ probability calculation, it retrieves values for the event type, favorable outcomes, and total outcomes. It then calculates and formats the probability, storing the result in the
`result`

variable.- For ‘multiple’ probability calculation, it retrieves values for multiple events (e.g., eventA, eventB, eventC) and their respective favorable and total outcomes. It calculates individual probabilities for each event and computes the combined probability (
`probabilityABC`

). The result is then formatted and stored in the`result`

variable.- Finally, it updates the content of an HTML element with the id ‘result’ to display the calculated probability.
## How to use these functions:

Setting Calculation Type:

- Call
`setCalculationType('single')`

to switch to single probability calculation.- Call
`setCalculationType('multiple')`

to switch to multiple probability calculation.Calculating Probability:

- Call
`calculateProbability()`

after setting the calculation type to perform the probability calculation.- The result will be displayed in an HTML element with the id ‘result’.

## How To Implement

Implementing this Confidence Interval Calculator on WordPress involves a few steps. Here’s a step-by-step guide:

**1. Access WordPress Admin Dashboard**

Log in to your WordPress admin dashboard.

**2. Create a New Page**

Navigate to Pages > Add New in the WordPress admin.

Give your page a title, such as “Confidence Interval Calculator.”

**3. Switch to HTML Editor**

On the page editor, switch to the HTML editor. Look for a tab that says “HTML” or “Code.”

**4. Copy HTML Code**

Copy the entire HTML code (from <!DOCTYPE html> to the closing </html>) from your index.html file.

**5. Paste HTML Code**

Paste the copied HTML code into the HTML editor of your WordPress page.

**6. Add CSS**

Copy the entire CSS code (from the <style> tag in the styles.css file) and paste it into the WordPress page’s HTML editor, preferably within the <head> section.

**7. Add JavaScript**

Copy the entire JavaScript code (from the <script> tag in the script.js file) and paste it into the WordPress page’s HTML editor, preferably just before the closing </body> tag.

**8. Save and Publish**

Save the changes to your WordPress page.

Click the “Publish” button to make the page live.
