Random and Probabilty

Question

Hello!
I have been trying to wrap my head around the discrete_distribution method of random and am having troubles.

I want to use it to produce a random value between one and ten with lower numbers having a higher probabilty of being generated. say 1-5 a 75% chance, 5-8 a 20% chance and finally 9-10 a 5% chance.

I have gotten some sample code (see below) from the interwebs but am unsure of how to use it to weigh chances.

Am I even on the right track?

Answer 1

I *think* I understand.

when using discrete_distribution each value in the array of weights represents a number starting from 0.

So;

discrete_distribution<int> dist { 2, 1};

is like saying pick between 0 and 1 where 0 has a 50% higher chance of being returned

Maybe?
