         Two die are cast. What is the
         probability that two fours will
         be shown?
         Because it it is difficult in this case
         to draw a tree-diagram, we will rather
         use a table to write down all
         the outcomes.
         The outcomes are written down as
         double-digit numbers e.g.
         32 will represent a 3 on the first die
         and a 2 on the second die.
         The table is shown below :
  

         11.1  Vul die ontbrekende getalle in,
  
           Bereken die waarskynlikheid om
           die volgende te kry
  
         11.2  twee viere
  
         11.3  'n 3 en 'n 4, in enige volgorde
  
         11.4  'n 3 en 'n 4, in daardie volgorde
  
         11.5  twee onewe syfers
  
         11.6  elke syfer kleiner as 3
  
         11.7  elke syfer 'n veelvoud van 3
  
         11.8  die som van die twee
                  syfers is 7
  
         11.9  die som van die twee
                  syfers is groter as 9
  
         11.10  twee gelyke syfers
  
         11.11  die verskil van die twee
                    syfers is kleiner as 3
  
         11.12  die som van die twee syfers
                    is gelyk aan 7
  
         11.13  die som van die twee syfers
                    is kleiner as 13
  
         11.14  die som van die twee syfers
                    is groter as 15
  
         11.15  die produk van die twee syfers
                    is gelyk aan 20
  
         11.16  die produk van die twee syfers
                    is groter as 18

         Calculate the probability to get
         the following

                    smaller than 13
  
         11.14  the sum of the two digits is
