   How many times a year does a double follow a double in pick 3 ??

            What's the expected math average ? 

                             

   

              My gut says about 12 to 20 per yr.

   

    Now ...that's just a double double ...... not counting those times it goes 3 or 4 or 5 doubles in a row.

   

          * By the way .....my guess is 2 to 3 times a year we will get 5 doubles in a row.

   

                   In a 365 day year .... we can expect approx 99 doubles a year ......and 263 Singles.

  Thanks for these Stats Win D

  Love em!

  According to the posted topic - Discharging Reoccurrence Distribution, this value can be found for any reoccurrence of any phenomena. Just plug in the values.

      Discharge Reoccurrence - y = (d / m² ) e ^{-(x / m )}

        d - total number of draws
        m - average rate of reoccurrence
        x - draw difference or Dd between two draw occurrences 
        y - the approximate frequency of reoccurrence for a given draw difference or Dd for a given draw count d

  The values in this case are d = 365 (draws, assuming drawn every day), m = 1000 / 270 (total outcomes / total occurrences) , x = 1 (draw difference or one draw to the next).

  The formula becomes:

  y = (365 / (1000 / 270)² ) e ^{-(1 / (1000 / 270) )}     

  y = (365 * (270 / 1000)² ) e ^{-(270 / 1000)}     

  y = (365 * (0.270)² ) e ^-0.270     

  y = (365 * 0.0729) * 0.7634     

  y = 26.6085 * 0.7634     

  y = 20.3129 (occurrences in 365 days or draws)
