Let x determine a random variable, and use your knowledge of probability to prepare a probability distribution. A family has two children and the number of girls is recorded. (Assume an equal chance of a boy or girl for each birth.) Complete the probability distribution. x \( \mathrm{P}(\mathrm{x}) \) (Type an integer or a simplified fraction.)

In a family with two children, there are four possible combinations regarding the gender of the children: Boy-Boy (BB), Boy-Girl (BG), Girl-Boy (GB), and Girl-Girl (GG). To find the number of girls (x) for each outcome: - 0 girls (BB): 1 way - 1 girl (BG and GB): 2 ways - 2 girls (GG): 1 way Now, let's compute the probability for each outcome. Since there are a total of 4 combinations, the probabilities are: - \( P(0 \text{ girls}) = \frac{1}{4} \) - \( P(1 \text{ girl}) = \frac{2}{4} = \frac{1}{2} \) - \( P(2 \text{ girls}) = \frac{1}{4} \) So the completed probability distribution looks like this: x | \( P(x) \) 0 | \( \frac{1}{4} \) 1 | \( \frac{1}{2} \) 2 | \( \frac{1}{4} \)
