Actually I don’t want to reduce by the number 5,I want to keep all numbers that contain 5. For example if the last drawing is 531, after I filter my highs and lows,even and odds, I would like to filter and keep all numbers that contain 1 or more digit from the previous drawing. So i would see a list like 581, 322, 189 and would reduce number like 426, 982. I remember reading somewhere that the probability of at least one digit returning is a little over 60%.
