Probability of something appearing[need help]

Hi, im programming a fruit machine as part of an IT course. So far i have gone through making it pretty easily, but have got to, i cant work out how to change how probable it is of a fruits appearing, like cherries more likely to appear than bells. I also need help with having the ability to hold. below is the code of my program(prepare for scrolling).
-----------------------------------------------------------------------
program fruitmachine;

uses crt;

var bet,semibank,spin,bank,winings,yahoo,endscreen,endscreenwin,mulitplier,holdyn,checker,check,check1,written,blob,hold5050,rand:integer;
var fruit : array[1..9] of string;

begin
repeat
cursoroff;
//Initialising fruits
fruit[1]:=' cherry ';
fruit[2]:=' banana ';
fruit[3]:=' lemon ';
fruit[4]:=' orange ';
fruit[5]:=' bar ';
fruit[6]:=' melon ';
fruit[7]:=' coconut ';
fruit[8]:=' bell ';
fruit[9]:=' butter ';
