Lotto history buffs read a whole lot more into the significance of a Lotto draw history than it warrants including giving each history a special relationship with numbers that are subsequently picked. Basically it is just a bunch of random combinations for the prescribed Pool and Pick and whatever conclusions pertain to one history apply to another of like Pool and Pick. To ask from 3 draws what integers were in the previous 2 draws is no different to asking from 3 random selections as per the parameters of the Lotto game what integers in the last selection were in the previous 2 selections.

The following table analyzes 1636 draws of the UK 6/49 Lotto game and shows the integer repeats (or matches with the considered draw) for up to 6 draws prior to the considered draw. There is nothing useful in doing this to pick your numbers to play but it is handy to have the facts when dealing with predictionists that try to turn it around the other way and get numbers to play from those that have already occurred.

A quick check mathematically for the previous draw with 0 repeats can be done by dividing the possibilities excluding 6 integers ie 43c6 by that for all possibilities ie 49c6. The calculation is 6096454/13983816 = 0.435936 or 44% which is close to the empirical value of 42%.

Lotto Draws have no relationship to one another; the integers serve just as identifiers. Any prediction calculation on one history of draws for a same type game is just as irrelevant as another.
