**Probability Distribution of the Number of Girls in 8 Births**

This educational resource explores probability distributions by examining the number of girls born in a sample of 8 births from different sets of parents. The random variable \( x \) represents the number of girls among the 8 children. The goal is to find the mean and standard deviation for this distribution.

**Table: Number of Girls and Probabilities**

- **Number of Girls (x)** | **Probability \( P(x) \)**
  - 0 | 0.005
  - 1 | 0.027
  - 2 | 0.114
  - 3 | 0.223
  - 4 | 0.275
  - 5 | 0.214
  - 6 | 0.111
  - 7 | 0.028
  - 8 | 0.003

**Instructions:**
- Calculate the mean \((\mu)\) by multiplying each number of girls by its probability and summing these products.
- Calculate the standard deviation \((\sigma)\) by determining the variance first, which involves computing the squared differences from the mean, weighted by their probabilities, and taking the square root.

Please round your answers to one decimal place as needed.
