How do I add probability to Choose ?

Choose expression is very interesting but every item in it has the same probability to come out.

Is there a possibility to add probability so that when Choose(a,b,c) is called, I have 50% chances to have 'a' and 25% chances to have 'b' or 'c' ?

You can use the Advanced Random plugin to create a probability table.

Thanks.

Do you have an example for this ? I had a look and it seems quite obscure to me
