🔍 Probability Distributions at a Glance
| Distribution | Probability Function | Mean and Variance |
|---|---|---|
| Binomial | P(X=k) = C(n,k)p^k(1-p)^(n-k) | Mean: np, Variance: np(1-p) |
| Poisson | P(X=k) = (e^(-λ)λ^k)/k! | Mean: λ, Variance: λ |
| Normal | f(x) = (1/(σ√(2π)))e^(-(x-μ)²/(2σ²)) | Mean: μ, Variance: σ² |
💡 Expert Problem-Solving Techniques
