Question
Suppose that the genders of the three children of a certain family are soon to be revealed. Outcomes are thus triples of "girls" (g) and "boys" (b), which we write as gbg, bbb, etc. For each outcome, let \( R \) be the random variable counting the number of girls in each outcome. For example, if the outcome is bgb, then \( R(bgb) = 1 \). Suppose that the random variable \( X \) is defined in terms of \( R \) as follows: \( X = 2R - 2R^2 - 3 \). The values of \( X \) are given in the table below.

| Outcome | ggg | gbg | bgb | bbb | bbg | ggg | ggb | gbb |
|---------|-----|-----|-----|-----|-----|-----|-----|-----|
| Value of \( X \) | -15 | -7 | -3 | -3 | -3 | -7 | -7 | -3 |

Calculate the values of the probability distribution function of \( X \), i.e. the function \( p_X \). First, fill in the first row with the values of \( X \). Then fill in the appropriate probabilities in the second row.

| Value \( x \) of \( X \) | ??? | ??? | ??? |
|--------------------------|-----|-----|-----|
| \( p_X(x) \)             |     |     |     |

The accompanying graphic appears to be a partial table meant to calculate the probability distribution of the variable \( X \). The placeholders indicated by question marks suggest that users should determine the distinct values of \( X \) and their corresponding probabilities based on the outcomes provided.
