std::discrete_distribution
std:: vector < double > probabilities ( ) const ;
(C++11 이후)

이 분포에 의해 생성되는 각 정수의 개별 확률을 포함하는 std:: vector < double > 를 얻습니다.

매개변수

(없음)

반환값

std:: vector < double > 타입의 객체입니다.

예제

이 코드 실행 
#include <iostream>
#include <random>
#include <vector>
int main()
{
    std::discrete_distribution<> d({40, 10, 10, 40});
    std::vector<double> p = d.probabilities();
    for (auto n : p)
        std::cout << n << ' ';
    std::cout << '\n';
}

출력: 

0.4 0.1 0.1 0.4
