Struct rand_distr::Binomial

source ·
pub struct Binomial { /* private fields */ }
Expand description

The binomial distribution Binomial(n, p).

This distribution has density function: f(k) = n!/(k! (n-k)!) p^k (1-p)^(n-k) for k >= 0.

Example

use rand_distr::{Binomial, Distribution};

let bin = Binomial::new(20, 0.3).unwrap();
let v = bin.sample(&mut rand::thread_rng());
println!("{} is from a binomial distribution", v);
