  How many different Straight Combinations can we make with these 5 positions using 2 digits 

 

                                                 1 and 2 

 

12222 21111    12121 21212     11122 22211

12211 21122    22221 11112    22112 11221

11222 22111   21222 12111    21121 12212

21221 12112   22122 11211   21122 12211

22121 11212   12122 21211    12121 21211

11121 22212  

 

                                                                   I did 32 and had vapor lock !   Oogle 

 

 

The only real failure .....is the failure to try.                               

                              Luck is a very rare thing....... Odds not so much. 

                              Odds never change .....but probability does. 

                                                                                       Win d

       Here is a different way to look at it .....as a 5 number game using ODD /Even rather than 1 and 2 digits.   

       So.....we can see there are only 7 versions (Box wise) in a 5 postion game.

         

      ODD / EVEN SETS
      5 Number Games6 Number Games
      3 odd / 2 even3 odd / 3 even
      2 odd / 3 even4 odd / 2 even
      4 odd / 1 even2 odd / 4 even
      1 odd / 4 even5 odd / 1 even
      5 odd / 0 even1 odd / 5 even
      0 odd / 5 even6 odd / 0 even
      0 odd / 6 even

       

       

      The only real failure .....is the failure to try.                               

                                    Luck is a very rare thing....... Odds not so much. 

                                    Odds never change .....but probability does.
