Here is the idea

pawn Код:

new RandomCash[] = 
{
    100,
    100,
    100,
    150,
    150,
    1000
};



//then
   new Random = random(sizeof(RandomCash));
    GivePlayerMoney(playerid, RandomCash[Random]);

100$ will have the most chance to be gotten

EDIT: Too late, BroZeus already posted the solution
