std::discrete_distribution
 

Template:ddcl list begin <tr class="t-dcl ">

<td >
std::vector<double> probabilities() const;
</td>

<td class="t-dcl-nopad"> </td> <td > (since C++11) </td> </tr> Template:ddcl list end

Obtains a std::vector<double> containing the individual probabilities of each integer that is generated by this distribution.

Parameters

(none)

Return value

An object of type std::vector<double>

Example

Run this code
#include <iostream>
#include <vector>
#include <random>
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';
}

Output: 

0.4 0.1 0.1 0.4
