Mean

Standard Deviation

Discrete Random Variables

### Formulas

Mean (μ) = Σ[x * P(x)]

Standard Deviation (σ) = √Σ[(x - μ)^2 * P(x)]

Various Probability calculations based on the distribution: P(more than 3 girls), P(at least 3 girls), etc.

### Theorems

Basic Probability Theorem

Properties of Discrete Probability Distributions

### Suitable Grade Level
