## Examples

```swift

import Random

var random: PseudoRandom = .init(seed: 13)

let binomial: (Int64, Int64, Int64, Int64) = (

    Binomial[10, 0.2].sample(using: &random.generator),

    Binomial[10, 0.2].sample(using: &random.generator),

    Binomial[10, 0.2].sample(using: &random.generator),

    Binomial[10, 0.2].sample(using: &random.generator),

)

// Generated binomial samples: (1, 4, 2, 4)

let normal: (Double, Double, Double, Double) = (

    Normal[0, 1].sample(using: &random.generator),

    Normal[0, 1].sample(using: &random.generator),

    Normal[0, 1].sample(using: &random.generator),

    Normal[0, 1].sample(using: &random.generator),

)

// Generated normal samples: (1.031, 1.201, -1.607, -0.243)
