1.       1.1)P(number 6) = 1/6 = 0,167 =17% Rounded off 

            W(nommer 6) = 1/6 = 0,167 = 17% (afgerond)

                   

1.2)P(odd number) = 3/6 = 1/2 = 0,5 = 50% 

      W(onewe getal) = 3/6 = 1/2 = 0,5 = 50% 

1.3)P(number 2 or 4) = 2/6 = 1/3 = 0,33 = 33% Rounded off                  

      W(nommer 2 of 4) =  2/6 = 1/3 = 0,33 = 33% (afgerond)

2.       2.1) P(red sweet) = 5/9 =0,56 = 56 % rounded off                                 

              W(Rooi) =5/9 =0,56 = 56 % (afgerond)

2.2) P(green sweet) = 3/9 = 1/3 = 0,33 = 33% Rounded off                    

        W(Groen) = 3/9 = 1/3 = 0,33 = 33%  (afgerond)

2.3) P(green or orange sweet) = 4/9 = 0,44 = 44% Rounded off       

        W(Groen of oranje) = 4/9 = 0,44 = 44%  (afgerond)

3.       3.1) P(1 teddy bear) = 1/10 (10%)                                                                   

              W(1 Beertjie) = 1/10 (10%)

3.2) P(teddy bear[1 or 2]) = 2/10 = 1/5 (20%)                                                  

       W(beertjie [1 of 2]) = 2/10 = 1/5 (20%)

3.3) P(a winner) = 3/10 (30%)                                                                           

       W(‘n wenner) = 3/10 (30%)

3.4) No, because there is only a 30% chance of winning with the game. You have 70% chance of losing with this game. You may have a chance of winning but there is a bigger chance of losing.

Nee, want daar is slegs ‘n 30% kans om die spelletjie te wen. Jy het 70% kans om te verloor. Jy kan dalk wen maar daar is ‘n grootter waarskynlikheid dat jy gaan verloor as gaan wen.
