Question
## Sampling Distribution of the Sample Proportion of Girls from Two Births

Consider a scenario where two births are randomly selected. The sample space for gender combinations from these births is:
- bb (both boys)
- bg (first boy, second girl)
- gb (first girl, second boy)
- gg (both girls)

Assume that these four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births.

### Assumptions

1. The probability of having a boy is \( \frac{1}{2} \).
2. The probability of having a girl is \( \frac{1}{2} \).
3. These probabilities are unaffected by previous births.

### Task

Determine the probabilities of each sample proportion of girls.

### Table Format

| Sample Proportion of Girls | Probability |
|----------------------------|-------------|
|                            |             |
|                            |             |
|                            |             |

Enter your answers in the editable fields of the table and click "Check Answer" to verify.

### Interface Guide

To input your answers:
1. Click on the dropdown menus under "Sample Proportion of Girls" to select the appropriate values.
2. Type the probability values in the provided fields under "Probability."

After entering your answers, click the "Check Answer" button to evaluate your entries.

**Note:** The interface includes tools such as clear all entries and navigate to the next section buttons. The current status of completion is indicated by a progress bar.

**Example:**
- If the sample proportion of girls is 0, the probability would be the likelihood of having two boys (bb).
- If the sample proportion of girls is 0.5, the probability would be the combined likelihood of having one boy and one girl (bg or gb).

Complete the table based on these logical deductions and verify to ensure the sample proportion accurately reflects the population proportion.
